Long, Ethan *The Wing Wing Brothers Math Spectacular!*

**Gr. K–3 ** 32 pp. Holiday

In three acts, five performing duck brothers compete with one another and introduce basic math concepts by spinning plates, juggling pies, and disappearing in a box. The simple cartoony panels give the book a comic-book appearance, and humor abounds via sibling rivalry, slapstick elements, and even a flatulence joke. An appended note addresses Common Core State Standards for kindergarten mathematics.

Marzollo, Jean *Help Me Learn Subtraction*

**Gr. K–3** 32 pp. Holiday

Photographs by Chad Phillips. Rhyming sentences describing equations (“10 monsters looking fine! / 1 folds down. / Still up? 9!”) help put subtraction in context for young learners. Photographs of monster finger puppets, pipe-cleaner dogs, and other trinkets illustrate each problem. A letter at book’s end connects the content with Common Core State Standards and gives parents and teachers ideas for other activities.

Menotti, Andrea *How Many Jelly Beans?: A Giant Book of Giant Numbers!*

**Gr. K–3** 24 pp. Chronicle

Illustrated by Yancey Labat. When asked how many jelly beans they would like, Emma and Aiden both start off small — then each one-ups the other, naming progressively higher numbers until they amusingly stop at one million (depicted in a poster-size gatefold). Labat’s clean digital illustrations, featuring black-and-white figures and colorful candies, break down conceptually challenging large numbers by arranging them in creative ways.

Neuschwander, Cindy *Sir Cumference and the Viking’s Map: A Math Adventure*

**Gr. 4–6** 32 pp. Charlesbridge

Illustrated by Wayne Geehan. Cousins Per and Radius hunt for treasure by unraveling a Viking mapmaker’s clues: a series of coordinates (x, y) that pinpoint locations on the Viking’s map grid. In a rather superfluous subplot, highway robbers, channeling the Keystone Kops, chase the cousins around. Acrylic paintings with a medieval setting illustrate this introduction to coordinate (a.k.a. Cartesian) planes.
