About the Holiday

National Math Storytelling Day was established in 2009 by Maria Droujkova, founder of The Natural Math Community at Naturalmath.com, and her daughter to encourage people to share the joys of math with children through stories and games. Having fun with math is one of the best ways to get kids excited about learning and working with this most important subject. Celebrate today with math stories that involve patterns, spatial relations, quantities, logic, puzzles, and numbers. You can even sing math songs and tell math jokes! You’ll find lots of resources for Math Storytelling Day and every day on the Natural Math website.

How to Code a Rollercoaster

Written by Josh Funk | Illustrated by Sara Palacios

 

Pearl and her robot Pascal are ready to enjoy a day at the amusement park. Pearl can’t wait to ride the Python Rollercoaster, and after she buys her tokens she decides to map out the perfect day at the park. With so many games and rides to line up for, Pearl thinks using code—“a set of instructions that computers understand”—will be the best way to go about it. She has ten tokens for the day, and can keep track of how many uses and has left “by using a variable,” which is like a “container…that holds information.” Pearl names her variable MyTokens, and they’re off and running. (Lucky for Pascal, robots ride for free!)

When they get to the Python Rollercoaster, the line snakes far into the park, so they head for the Ferris wheel. Pearl loves Ferris wheels and thinks once around isn’t enough. Each trip around costs one token, so Pearl codes a LOOP to “subtract 1 token from MyTokens” each time they “start a new ride.” After three times around, they get off and consider checking out the line for the Python Coaster again. But what will they do if it’s still too long? Another variable can solve that problem.

This one Pearl names ShortLine. She gives it a value of true or false and uses “an if-then-else to decide what to do next.” So, “IF ShortLine is True THEN we’ll ride the Python Coaster ELSE we’ll do something fun on the map,” she explains to Pascal. When they get to the rollercoaster, ShortLine is False and the line is still long, so they ride the log flume. Pascal reminds Pearl that they have six tokens left. They check the IF-THEN-ELSE again and again and again and take a trip on the train, play a target game, and twirl in the teacups.

After a stop at Reshma’s ice cream stand and a delicious treat, Pearl and Pascal check the Python again. Finally, ShortLine is True. But it takes two tokens to ride and Pascal tells Pearl she has only one token left. Just then Pearl sees a sign offering a way to win a free token. All they need to do is find special stars around the park and figure out a secret password. Pearl knows she can use another variable to solve the puzzle.

celebrate-picture-books-picture-book-review-how-to-code-a-rollercoaster-long-line

Image copyright Sara Palacios, 2019, text copyright Josh Funk, 2019. Courtesy of Viking.

Pearl and Pascal retrace their steps and find the stars along the way. But the letters don’t spell anything. Suddenly, Pearl understands that they need to put the “letters into the correct sequence to figure out the secret password…just like how code needs to be in the proper sequence to work correctly.” Once they know the password, they’re psyched for the thrills and chills of the Python Coaster.

Back matter includes Pearl and Pascal’s Guide to Coding, which gives more information on the terms found in the story. A foreword written by Reshma Saujani, the founder of Girls Who Code, invites readers to learn more about the organization and welcomes children to the world of coding.

To kids’ delight Josh Funk’s Pearl and Pascal are back in another coding adventure—this time at the Gigaworld Amusement Park. They’re excited to ride the Python rollercoaster, but the super long line gives them a chance to code a day of fun in the rest of the park. Young coders and would-be coders will love joining these two best friends on favorite rides as they learn procedures that make programs run smoother and help determine various outcomes. Pascal is as literal as ever, leading to some funny moments of misunderstanding. Funk also includes some nods to his computer programmer day job for eagle-eyed readers. Pearl’s enthusiasm for using code to navigate the park is infectious and will entice kids to explore the world of coding either just for fun or as a future career.

You can almost smell the popcorn and hear the squeals of joy emanating from Sara Palacios’ pages as Pearl and Pascal run through their day at the amusement park. From the Ferris wheel to the log flume to the teacups and the midway, Palacios’ colorful and action-packed illustrations put readers in the center of the fun. Through Pascal’s display function, Palacios clearly labels the variables, values, and loops used during the day as well as the token countdown that leads to the secret code scavenger hunt. Readers will definitely want to return to the first page and read the book again to find all of the lettered stars themselves.

Pearl’s passion for coding and Pascal’s responsiveness is sure to inspire children to explore the wonders of coding and computer science. As part of the Girls Who Code program, the book is especially designed to encourage girls to get involved in computer programming and STEM. How to Code a Rollercoaster is a rousing choice for home, classroom, and public library bookshelves.

August 3 – National Twins Day

celebrate-picture-books-picture-book-review-twinderella-cover

About the Holiday

Today’s holiday got its start in 1819 when identical twins Moses and Aaron Wilcox agreed to donate six acres of land to the town of Millsville, Ohio if they would change the name of the town to Twinsburg. They did! In 1976, Twinsburg established an annual festival for twins. Only thirty-six twins attended that first festival, but today the three-day event attracts more than 2,000 twins from all over the country. The weekend includes golf and volleyball tournaments, kids’ games, a parade, amusement rides, entertainment, fireworks, and, of course, twins contests and talent contests. For more information on this unique festival, visit the Twins Days Festival website.

Twinderella, A Fractioned Fairy Tale

Written by Corey Rosen Schwartz | Illustrated by Deborah Marcero

 

You, of course, know the story of Cinderella, but did you know that she had a twin named Tinderella? Here’s how the whole story goes…. When the two girls were given their long list of chores by their wicked stepmother, “Tinderella split each task / exactly down the middle. / Twelve to fix? / That’s six and six. / She’d solve it like a riddle.” And, thus, Cinderella and Tinderella went to work on fixing the household’s clocks.

The girls also split the mopping, shopping, baking, mending, and “the mean stepsister tending.” Left with only leftovers to eat at the end of the day, the two even shared half a piece of bread and half the scraps before collapsing into their half of the bed. In their  dreams, Cinderella kept her eye on marriage while Tinderella calculated what having twice the room would be.

celebrate-picture-books-picture-book-review-twinderella-chores

Then one day, the sisters saw an open invitation by the prince to a ball where he hoped to find his princess. Cinderella was excited that her dream could come true, but her stepmother told them they had to stay home to clean. “So Cinderella grabbed a broom, / but as she started sweeping, / she felt her dreams all turn to dust / and couldn’t keep from weeping.” But suddenly their fairy godmother appeared, and with her magic wand she created two beautiful gowns, two pairs of slippers, and lots of other bling. Tinderella split all of this between them, and as they each climbed into their half of a fabulous car, they listened to the fairy godmother’s warning to be back by midnight.

As soon as the prince saw Cinderella and Tinderella, he was enchanted. “No other girl stood half a chance—he danced with them all night.” Taking turns with the Prince, the girls danced the night away until they heard the clock begin to chime. They ran away from the ball, leaving the saddened prince—and a shoe—behind. He tried the shoe on all the girls in the village until he found that it fit Cinderella and Tinderella.

celebrate-picture-books-picture-book-review-twinderella-half-the-chores

Image Copyright Deborah Marcero, 2017, text copyright Corey Rosen Schwartz, 2017. Courtesy of G. P. Putnam’s Sons.

The prince didn’t know what to do and told the girls they had to choose. But Tinderella had a brilliant idea. She summoned their fairy godmother and asked if she could make the prince a twin. Before she did, though, Cinderella reminded the prince that he’d have to share his kingdom and all its wealth. “Prince Charming crossed his heart and swore / to split things even steven. / ‘I’d gladly give up all my stuff. / It’s love that I believe in.’”

With that the fairy godmother waved her wand and Whoosh! an exact double of the prince appeared. It turned out that he was just as much a whiz at math as Tinderella, and within moments he had neatly “divvied up the royal wealth” and won Tinderella’s heart. While Cinderella and Prince Charming ruled the kingdom, Tinderella and her prince ruled the math world. Later, Cinderella had a baby boy. And Tinderella? Well, “against all odds” she “delivered quads,” and everyone lived “happ’ly ever half-ter.”

An included poster allows kids and teachers to extend the math learning with entertaining activities on the back.

Fans of Corey Rosen Schwartz and her fractured fairy tales know all about her awesome storytelling and rhyming abilities. In Twinderella, A Fractioned Fairy Tale, she uses her multiple talents to give a favorite fairy tale a double dose of magic while engaging kids in a bit of math fun. Her always-clever verses shine with evocative vocabulary that gives the two girls distinct personalities while also ingeniously introducing the concept of one half and division. Schwartz doesn’t stop at a purely mathematical definition of these ideas, though. When Tinderella suggests making a double of the prince, Cinderella ensures Prince Charming is up to splitting his kingdom, in this way passing on her well-earned sense of empathy and sharing to readers. The sweet ending offers quadruple the delight of the original tale and prompts readers to dip into the story again to see how the girls’ fancy dress accessories and the princes’ kingdom along with other items in the story could be divided into fourths.

celebrate-picture-books-picture-book-review-twinderella-castle

Deborah Marcero’s mixed media illustrations are as charming as the prince himself. As red-haired Cinderella and Tinderella go about their copious chores, thumbnail portraits of the girls splitting the work demonstrate the idea of one half. A larger image of the girls baking reveals the opportunities for math learning in this everyday activity. A pie chart that Tinderella draws on a chalkboard is clearly labeled and corresponds to the clocks on the table, introducing kids to this graphing system and allowing them to make connections. Similarly, the concept of area is portrayed as Tinderella dreams of a bigger bed. A careful look on every page will reward readers with many chances for counting and dividing at various levels depending on the age of the reader. Marcero’s color palette is fresh and vibrant while infusing the pages with a royal ambience that hints at the girls’ enriched future.

A joy to read aloud, Twinderella, A Fractioned Fairy Tale is an enchanting story that doubles as inspired math learning. The book would be a favorite addition to any home, classroom, and public library collection.

July 8 – Math 2.0 Day

celebrate-picture-books-picture-book-review-a-million-dots-cover

About the Holiday

Today’s holiday celebrates the merging of math and technology together as the foundation of most of the things we use every day, such as computers, phones, tablets and other electronics. Math and technology are also employed by architects, scientists, researchers, and manufacturers. Math 2.0 Day was established to bring together mathematicians, programmers, engineers, educators, and managers to raise awareness of the importance of math literacy at all levels of education.

A Million Dots

By Sven Völker

 

With one green dot (and one brown rectangle) you can make a tree. Add one plus one and you can make two trees. Two plus two? Well, four trees might get a little boring. Why not put two apples on each tree? Then four people can enjoy a snack. In the autumn, those apples fall. There are four plus four dots on the ground—how many does that make? Eight!

celebrate-picture-books-picture-book-review-a-million-dots-four

Eight plus eight? A nice number of dots for a ladybug’s wings. Won’t you count them? How about  adding those sixteen to another sixteen? Those thirty-two dots are still contained in a box. But thirty-two plus thirty-two? At sixty-four the dots spill out, colorful and free! Sixty-four plus sixty-four dots make one hundred and twenty-eight bubbles in a fizzy drink. Add one hundred and twenty-eight to itself and what do you get? A face full of freckles! What happens if you keep adding and adding? What can you make? Two thousand and forty-eight plus two thousand and forty-eight makes a night sky of stars, their reflections on the sea and the lights on the ship that sails it.

celebrate-picture-books-picture-book-review-a-million-dots-sixty-four

Copyright Sven Völker, 2019, courtesy of Cicada Books and svenvolker.com.

Thirty-two thousand, seven hundred and sixty-eight plus thirty-two thousand seven hundred and sixty-eight makes sixty-five thousand, five hundred and thirty-six—enough dots for a soccer field to mow. Twice that is a desert of sand to scoop. Moving on to two hundred and sixty-two thousand, one hundred and forty-four plus the same, a blanket of steam streams out of a train stack five hundred and twenty-four thousand, two hundred and eighty-eight dots long, past the coal car and the long tanker car.

But what can be made when these half-a-million dots and a little are added together? One million and forty-eight thousand, five hundred and seventy-six dots filling apartment buildings, office towers, and inspiring skyscrapers in a fabulous city—maybe it’s yours!

celebrate-picture-books-picture-book-review-a-million-dots-one-hundred-twenty-eight

Copyright Sven Völker, 2019, courtesy of Cicada Books and svenvolker.com.

One, two, ten, even one hundred—you can see that number of people or items in your mind. It’s hard, though, especially for children, to visualize a thousand, a hundred thousand, a half a million, even a million. In his stylish book, Sven Völker translates these numbers into dots and uses them to create images that are both humorous and awe-inspiring. One dot nearly fills the page, but by the time the numbers have been doubled and doubled multiple times, half-a-million and then a million minuscule dots require pages that fold out and out and out and out…and out! Each number is presented in words and numbers allowing children to see and learn each interpretation. Kids who love numbers and counting and visual proofs will have a blast connecting these dots.

An entertaining and educational way to relay the idea of number to kids at home or in the classroom, A Million Dots will elicit multiple exclamations of “Wow!” as the numbers add up. The book is available for preorder and releases in the U.S. on September 13.

Ages 4 – 12

February 24 – National Tortilla Chip Day

celebrate-picture-books-picture-book-review-round-is-a-tortilla-a-book-of-shapes-cover-2

About the Holiday

If the tortilla-making machine had produced perfect rounds every time back in the 1950s, the world may never have known the crunchy deliciousness of tortilla chips. Back in the day, Rebecca Webb Carranza and her husband owned the El Zarape Tortilla Factory in Los Angeles, California and were one of the first to automate tortilla production. Instead of wasting the odd-shaped ones, Carranza cut them into triangles, fried them, and sold them in bags.They were a hit! People all over began enjoying them dipped in salsa and guacamole and smothering them in cheese. In 1994 Carranza was honored with the Golden Tortilla Award for her contributions to the Mexican food industry, and in 2003 Texas named the tortilla chip the official state snack!

Round is a Tortilla: A Book of Shapes

Written by Roseanne Greenfield Thong | Illustrated by John Parra

 

“Round are sombreros. / Round is the moon. / Round are the trumpets that blare out a tune. Round are tortillas and tacos too. / Round is a pot of abuela’s stew. / I can name more round things can you?” With wonderful, lyrical verses, Roseanne Thong introduces children to the shapes—circles, squares, triangles, rectangles, ovals, stars, and more—that make up their multicultural world.

celebrate-picture-books-picture-book-review-round-is-a-tortilla-squares

Image copyright John Parra, 2013, text copyright Roseanne Thong, 2013. Courtesy of Chronicle Books.

Here are round chiming campanas and nests full of swallows, square ventanas for peering through and clocks for telling time. Rectangles are cold paletas to eat on a hot summer day and the ice-cream carts that deliver them, and triangles make tasty quesadillas and gliding sailboats. Each verse ends with an invitation for kids to find more shapes around them—an invitation that’s hard to resist!

celebrate-picture-books-picture-book-review-round-is-a-tortilla-triangles

Image copyright John Parra, 2013, text copyright Roseanne Thong, 2013. Courtesy of Chronicle Books.

Rebecca Thong’s bright, fun-to-read verses shine with evocative words that create a concept book that goes beyond the introduction of shapes to celebrate the sights, sounds, and sensations that make up readers’ lives. Helping children find shapes in household objects, food, and other familiar places, makes them more aware of the math all around them. They will be excited to point out the squares, triangles, circles, and more that they encounter every day. Spanish words sprinkled throughout the story are defined following the text. 

celebrate-picture-books-picture-book-review-round-is-a-tortilla-star

Image copyright John Parra, 2013, text copyright Roseanne Thong, 2013. Courtesy of Chronicle Books.

John Parra’s beautiful folk-art illustrations, which are sure to put a smile on kids’ faces, immerse readers in the daily life of a Latino town. People dance, cook, play games, walk in the park, attend a festival, and more—all while surrounded by colorful shapes. Kids will love lingering over the pages to find all of the intricate details and may well want to learn more about what they see.

Round is a Tortilla is not only a book of shapes, it makes shapes exciting! The book is a wonderful stepping stone to discussions about early math concepts as well as the places, celebrations, symbols, and decorations found on each page. The book would be a welcome addition to any classroom or child’s bookshelf

December 7 – It’s Computer Science Education Week

celebrate-picture-books-picture-book-review-doll-E-1.0-cover

About the Holiday

Computer Science Education Week was launched in 2009 to raise awareness of the importance of computer coding in all careers and to invite people to learn how to code. Students from kindergarten to grade 12 are especially encouraged to take an interest in computer science and learn coding skills and also to take part in Hour of Code programs at school and elsewhere. The holiday is celebrated in December to honor computing pioneer Admiral Grace Murray Hopper, who was born December 9, 1906 and went on to become a United States Navy rear admiral. Her work with machine-independent programming languages led to the development of COBOL, and she was instrumental in many other early computer-related advancements. To celebrate this week, check out the Computer Science Education Week website and Hour of Code and try coding for yourself!

Doll-E 1.0

By Shanda McCloskey

 

“Charlotte’s head was always in the cloud.” She knew everything about computers and was plugged in to the (virtual) realities of each day. One day her mother bought her a present. Charlotte wondered at what kind of electronic marvel might lie underneath the wrapping. When the robotic arm she’d build untied the bow and tore off the paper, Charlotte gazed at the cloth doll in the little stroller uncertainly.

celebrate-picture-books-picture-book-review-doll-E-1.0-lab

Copyright Shanda McCloskey, 2018, couirtesy of Little, Brown Books for Young Readers.

She wasn’t sure how to play with it; where was the instruction manual? Charlotte took the doll to her lab and tried to engage it in her favorite video game and to get it to dance under the revolving disco ball, but the doll just sat on the floor and stared at her. Suddenly, the doll said “Ma-ma.” Charlotte didn’t think she was Mama material, but then she had a thought: “If the doll could talk, then it must have a power supply.”

Sure enough when she opened the back, she found two batteries. This was more like it! Since the doll’s only word seemed to be “Ma-ma,” Charlotte ran an update on it to increase its vocabulary. But before she could finish, her dog grabbed the doll by the leg and ran off with it. Before Charlotte could stop him, Blutooth had ripped the doll apart.

celebrate-picture-books-picture-book-review-doll-E-1.0-virtual-games

Copyright Shanda McCloskey, 2018, couirtesy of Little, Brown Books for Young Readers.

Charlotte collected the doll’s arms, legs, and head, gathered some more supplies, and went to work in her lab. “With a few spare parts and a bit of code, Charlotte changed the doll.” It looked at Charlotte with its bright eyes and smile and said, “H-e-l-l-o m-y n-a-m-e i-s D-o-l-l-E 1.0.” “And the doll changed Charlotte too.” Charlotte loved Doll-E. She read to it, and played with it, and took it outside, where its fast stroller and new remote-controlled robotic arms were perfect for walking Blutooth.

celebrate-picture-books-picture-book-review-doll-E-1.0-gift

Copyright Shanda McCloskey, 2018, couirtesy of Little, Brown Books for Young Readers.

Shanda McCloskey wonderfully inventive doll story for a new generation will delight children and remind adults that while toys may change, the feelings associated with them never do. Sprinkled with puns and led off with a just-right first line, McCloskey’s smart story shines. Charlotte shows heart and intelligence as she embraces her new doll and makes it a reflection of her own life—just as children have always done with their toys. Charlotte, as a computer whiz, makes a captivating role model for kids, especially girls who code or would like to.

There’s so much to admire in McKloskey’s illustrations, from Charlotte’s dedicated work space/lab outfitted with hand tools, spare parts, and craft supplies to her sweet determination to understand her new, simple doll. Clever details, such as a light bulb hanging over Charlotte’s head when she gets a brilliant idea and a Frankenstein-esque scene as Charlotte repairs her doll add depth and fun to the story’s theme.

A spirited story, Doll-E 1.0 clicks all the buttons as a must for home and classroom bookshelves.

July 17 – National Yellow Pig Day

The Boy Who Loved Math: The Improbable Life of Paul Erdős by Deborah Heiligman and LeUyen Pham picture book review

About the Holiday

Today’s holiday isn’t really about the color yellow or about pigs—it’s about math! Who knew? Well, plenty of people, actually! Mathematicians, college professors, and students spend the day celebrating the number 17 with special problems and yellow pig cakes, songs, parades, and more. The holiday was established in the 1960 when two Princeton University students, David Kelly and Michael Spivak began obsessing over the number 17. And the yellow pig? One story say it’s a reference to David Kelly’s collection of yellow pigs while another goes that the two concocted the idea of a yellow pig with 17 toes, teeth, eyelashes, etc. To celebrate, study up on the prime number 17 and have some more math fun!

The Boy Who Loved Math: The Improbable Life of Paul Erdős

Written by Deborah Heiligman | Illustrated by LeUyen Pham

 

In Budapest, Hungary a boy is born who loves math. His name is Paul Erdős and he lives with his mother, who loves him “to infinity” just as Paul loves her. When she goes back to work as a math teacher, she leaves Paul with Fräulein, his nanny. Fräulein loves rules and tries to get Paul to sit still, eat all his lunch, take a nap—to obey. But Paul hates rules.

Image copyright LeUyen Pham, 2013, text copyright Deborah Heiligman, 2013. Courtesy of usmacmillan.com.

At three years of age he teaches himself to count the days until his mother will be home with him 100 percent of the time. Knowing the number makes Paul feel better as his head is constantly full of numbers and what they can do. One day when he is four years old, he meets a woman and asks her two questions—what year she was born and at what time. When the woman tells him, it only takes him a moment to reveal how many seconds she has been alive.

Image copyright LeUyen Pham, 2013, text copyright Deborah Heiligman, 2013. Courtesy of usmacmillan.com.

He continues to play with numbers, learning more and more about the various types. He decides he will be a mathematician when he grows up. When Paul is old enough to go to school, he once again encounters rules he can’t abide. His mother decides he will be schooled at home, and even though this means more time with Fräulein, Paul considers it the better option.

There’s just one thing – while Paul thinks about numbers, Fräulein and his mother do everything for him. At meals they cut his meat and butter his bread; they dress him, and tie his shoes. When he becomes a teenager, he goes to high school and meets other kids who love math. He and his friends spend all their time doing math and by the time Paul is 20 he is famous around the world for his math equations.

There’s just one problem – even as an adult, Paul is so focused on numbers and math that he still doesn’t know how to do basic things for himself. When he is 21 he’s invited to go to England to work. At his first dinner there he stares at his bread and he stares at his meat. What is he supposed to do? With a little experimentation, he figures it out, but he also figures out that he sees the world in a different way.

He doesn’t want a normal life with a family and a house and a regular job. He designs for himself a very unusual lifestyle. Everything he owns fits into two suitcases, and with a little money in his pocket he flies from city to city to do math. He knows so many mathematicians that wherever he goes they invite Paul to stay with them. These families take care of Paul just as his mother and Fräulein had! They do his laundry, cook his meals, and pay his bills.

But even so, everyone loves “Uncle Paul!” He brings people together and shares his knowledge. His work in mathematics has given the world better computers, better search engines, and better codes for our spies to use. He was so admired that even now people represent their relationship with Paul by giving it a number – the “Erdős number.” Paul was a unique person who counted numbers and people as his best friends and experienced the world in a way that added up to a very special life.

Reading Deborah Heiligman’s The Boy Who Loved Math is a liberating experience. Her biography reveals not just what Paul Erdős did, but the quirky genius he was. It also honors all the people around the world who embraced his personality, allowing Erdős to focus on the work he was born to do. Heiligman’s engaging patter, full of interesting anecdotes, humor, and personality, is storytelling at its best and provides an absorbing look at a very unique life.

LeUyen Pham’s illustrations perfectly complement the text, exposing Erdős’s chafing under rules, his delight in math, and his development from youth to old age. Each fascinating page cleverly represents the way Erdős saw the world as numbers, equations, and geometric shapes appear on buildings, domes, and even in the very air! The text too is infused with numerals and mathematical symbols (“Paul loved Mama to ∞, too!), making this a prime book for any math lover!

About the Holiday

Today’s holiday celebrates the merging of math and technology together as the foundation of most of the things we use every day, such as computers, phones, tablets and other electronics. Math and technology are also employed by architects, scientists, researchers, and manufacturers. Math 2.0 Day was established to bring together mathematicians, programmers, engineers, educators, and managers to raise awareness of the importance of math literacy at all levels of education.

 

Hidden Figures: The True Story of Four Black Women and the Space Race

Written by Margot Lee Shetterly | Illustrated by Laura Freeman

 

“Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden were good at math…really good.” The United States was involved in World War II, and Dorothy wanted to help the war effort by working for the National Advisory Committee for Aeronautics to make planes faster, stronger, and safer. Developing new airplanes required lots of tests at the Langley Laboratory in Virginia. Today, we use computers to do the kinds of math needed, “but in the 1940s computers were actual people like Dorothy, Mary, Katherine, and Christine.”

Even though Dorothy was a woman and an African-American in the segregated South, Dorothy did not think her dream of getting a job was impossible. After all, she was really good at math. She applied and was hired as a computer. At Langley, whites and blacks worked in different buildings and had separate facilities. After the United States won the war, Dorothy stayed on to create better aircraft.

Now America and Russia were in competition to build the best airplanes. This required more math, more tests, and more computers. Mary Jackson was hired at Langley to test model airplanes in wind tunnels. Mary had her sights set on becoming an engineer, but most of the engineers were men. To prepare, Mary needed to take advanced math classes, “but she was not allowed into the white high school where the classes were taught.” Mary didn’t take no for an answer. She got special permission to take classes, got good grades, and “became the first African-American female engineer at the laboratory.”

In 1953 Katherine Jackson was hired for a team who tested airplanes while they were in the air. Her work was to analyze turbulence to make planes safer in dangerous gusts of wind. She wanted to go to her team’s meetings, but she was told by her boss again and again that it was impossible; women were not allowed to attend meetings. At last her persistence paid off, and she became the first woman to sign one of the group’s reports.

When machine computers were installed at Langley in the 1950s, they were faster than the human computers but made many mistakes. “Dorothy learned how to program the computers so they got the right answers and taught the other women in her group how to program too.”

In 1957 Russia launched a satellite into space, ramping up the competition with the United States. Now “the United States started building satellites to explore space too,” and the name of the agency was changed to the National Aeronautics and Space Agency or NASA. Then President John F, Kennedy set a goal of sending a man to the moon. First, however, there would need to be many experiments, new space craft, and tests to send astronauts into orbit. This meant more people who were good at math would be needed.

When the first manned space flight was planned, Katherine calculated the trajectory that would take John Glenn into space and bring him home again. In 1967 Dorothy Darden came to work at Langley. She loved electronic computers and wanted to become an engineer. “Her first job was to help with NASA’s mission to the moon.”

When Neal Armstrong stepped onto the moon’s surface for the first time on July 20, 1969, he said it was a giant leap for mankind. “It was also a giant leap for Dorothy, Mary, Katherine, Christine, and all of the other computers and engineers who had worked at the lab over the years.” The moon landing was just the beginning. NASA engineers were already dreaming of trips to other planets and super-fast spacecraft. And although it would be hard and require a lot of numbers, “Dorothy, Mary, Katherine, Christine knew one thing: with hard work, perseverance, and a love of math, anything was possible.”

Margot Lee Shetterly brings her compelling story Hidden Figures to children in this exceptional picture book that skillfully reveals the talents and dreams of Dorothy, Mary, Katherine, Christine as well as the work atmosphere and social injustices of the time period. While acknowledging the struggles and obstacles the four women faced, Shetterly keeps her focus on the incredible achievements of these brilliant women and the positive changes and opportunities for others they created. Brief-yet-detailed descriptions and explanations of math, science, and computer terms flow smoothly in the text, allowing all readers to understand and appreciate the women’s work.

As Dorothy, Mary, Katherine, Christine each begin their work at Langley as young women, Laura Freeman establishes their dreams and their particular field of expertise through richly colorful illustrations that highlight the schematics, tools, equipment, and models they used. In one particularly affecting spread, Dorothy, Mary, Katherine, and Christine go off to their offices on the left-hand side, and their white counterparts head out to theirs on the right-hand side while the blueprint of their building lies under their feet. Dorothy, Mary, Katherine, and Christine’s clothing is also mirrored in color by the women on the other side of the fold. Period dress and electronics show progression through the years, and kids may marvel at the size of early computers. The final image of Dorothy, Mary, Katherine, and Christine as older women is moving and inspirational.

Hidden Figures: The True Story of Four Black Women and the Space Race is an outstanding biography of four women who contributed their gifts for math as well as their self-confidence not only to science but to dreamers in their own and future generations. The book would be a stirring choice for classroom and home libraries.
