Awesum Alex, Math Detective: The Subtraction Problem

$ 20.00

The story about Gray is the tale of a young girl who goes to a new school and discovers, not just new friends, but a new way of approaching subtraction. Gone is the old method of crossing out smaller digits above larger digits, which confuses the issue of place value. Instead, children will learn alongside Gray, Alex, and their friends that there are several ways to do subtraction that allow them to use fundamental mathematical concepts logically—and to have fun in the process. In this volume, creative math educators Rachel McAnallen and Carol Ann Williams explain how to take the mystery out of subtraction.
