Less Than Zero

Perry the Penguin needs 9 clams to buy an ice scooter--but he's not very good at saving. As Perry earns, spends, finds, loses, and borrows clams, a simple line graph demonstrates the concept of negative numbers. This nonfiction picture book is an excellent choice to share during homeschooling, in particular for children ages 6 to 8. It's a fun way to learn to read and as a supplement for activity books for children.

This is a Level 3 MathStart book, which is perfect for kids ages 6 and up. The MathStart series uses funny stories and colorful art to show kids that they use math every day, even outside of the classroom! Each book features an activity guide to have fun with the math concepts presented in the story.
