The colorful, chunky bears that first appeared in Teddy Bear Counting introduce more advanced concepts like estimation, graphing, division, and multiplication in this squat book. McGrath uses rhyming verse to guide readers; on a spread containing a graph with the glinting beards divided by color, she advises: "Write down the total/you see in each row./Let's see if your guess/was too high or too low." Nihoff incorporates digital hands that point to and reach for the bears, emphasizing their resemblance to counting manipulatives. Though the beards feel surprisingly animated (especially when they open their arms and tumble in air), the book will be most effective when used with the bears' plastic counterparts (not included).
Similar in style to McGrath's Teddy Bear Counting, this picture book uses a rainbow of bears to explore sorting, graphing, addition and subtraction, multiplication and division, and ordinal numbers. Despite the rhyming text and bright illustrations hand drawn digitally in Adobe Photoshop, readers may get more out of Stuart J. Murphy's "MathStart" series (HarperCollins) or Greg Tang's math riddle books (Scholastic), where one concept is introduced as the topic for the book rather than several at once. This book would ake a great preview to using bear counters as math tools and is best suited for early-learning classrooms where children have access to these manipulatives.

Teddy Bear Math is a colorful book for children ages 58 that uses teddy bear counters to illustrate estimation, addition, subtraction, multiplication, and division. Graphing, comparing, and ordinal numbers are also included. The book could be used by teachers when working with teddy bear counters or other manipulatives. Each concept would need multiple representations to be sure children are understanding it. The excellent illustrations by Tim Nihoff and the rhyming prose make it a good read-aloud book, especially if the reader allows time for interaction from the children who are listening.
The design of the book might lead one to assume that it is appropriate for a younger audience. However, the speed and depth with which the mathematics is presented makes the book most appropriate for the indicated age level. Younger children might appreciate Teddy Bear Counting by the same author and illustrator.
