Nicole is a young student who struggles with math. For one thing, she keeps counting the same five fingers over and over. Then her friend, Jamie, shows her about number permanence using a variety of number models. She also explains the strategies of counting on and counting back to do addition and subtraction problems. Together at school, they learn even more models such as Cuisenaire rods, number lines, and base ten blocks from their teacher, Mrs. Cooper.

Written to be a springboard for early math lessons, this book explains each number model and includes practice pages for continued learning. Perfect for Kindergarten through second grade and for homeschool!
