Meet the kids in Mrs. Z's wacky and wonderful third-grade class! Synclaire Fields is proud to be the best in the class at math--until one mistake in a high-stakes situation means she's NOT the best after all. So who is she instead?

Synclaire Fields is the Math Kid in Mrs. Z's class, getting perfect marks on every quiz and helping her classmates master tricky concepts. She especially loves demonstrating her skills at her parents' store after school. Then she gets TWO ANSWERS WRONG on a math test, and ... How can she be the Math Kid if she isn't good at math anymore?

So Synclaire embarks on a quest to figure out what's next. Maybe she'll be a piano prodigy? A board-games whiz? A skating star? She likes some of these hobbies, but there's one constant with every role: She seems to come back to math. Maybe, with the help of her friends in Mrs. Z's class, she can still be the Math Kid after all?

Both sweetly poignant and laugh-out-loud funny, with black-and-white illustrations by Pura Belpr? Honor artist Kat Fajardo, Synclaire's story invites readers into Mrs. Z's class where friendship and fun rule the school, from NAACP Image Award finalist Olugbemisola Rhuday-Perkovich.
