"Kids, young and old, fall in love with math when they see how real-life and effortless it becomes thanks to these books." --Kimberly D. Mueller, Ed.D., First Grade Teacher, Ashbrook School, Lumberton NJ

100 Days of Cool is perfect for teaching numbers 1 through 100 to first, second, and third graders.

When Mrs. Lopez tells her class that they're going to celebrate "100 Days of School," Maggie hears "100 of Days of Cool" instead. Mrs. Lopez thinks that's a great idea, too. So for the next 100 days, Maggie, along with her buddies Nathan, Yoshi, and Scott, come up with 100 different ways to be cool. They wear funny glasses, fancy socks, decorate their bikes, even dress up in cloths from the wacky 1970s.
