Illustrated by Marie Hermansson
4 stars
Told with rhythm and rhyme, this book provides a fun and heartwarming presentation of prime numbers and remainders. A new student has joined the class of twelve and every reindeer is welcoming. But when they have to split up into groups to prepare for Showcase Night, they have a hard time figuring out how to make sure no one is left out.
A nice, visual representation of ways to divide by thirteen and the resulting remainder.
Includes explanations of remainders and prime numbers, and a quick lesson on how to help others when they’re feeling left out.
A sweet blend of math, teamwork, social awareness, and helping others. A nice combination with a heartwarming ending.
