Double Play!

K-Gr 2—A classroom full of animal students is released for recess. Jill and Jake, two monkeys, lead the line to the playground. "1 friend + 1 friend = 2 friends." Thus begins the exercise of doubling all the numbers from one to 10. Readers can follow the antics of all the characters on the playground and count the objects mentioned. Each spread has a math equation as well as a rhymed verse. When the bell rings, play ends and the two monkeys lead the line back inside. The large watercolor illustrations show a joyous romp through recess as the creatures blow bubbles, draw pictures, eat a snack, and generally have a good time. Young students will enjoy the book for its play aspect, not realizing that the math lesson is built into it. Every elementary school needs this one.—Ieva Bates, Ann Arbor District Library, MI
