Can you help me with my math homework?” If, like most parents, this question fills you with a sense of dread (or even panic), then this is the book for you.
So much for the “good old days” when elementary students simply memorized their times tables and struggled through long division. Today, students are expected not just to find the right answer, but also to choose the best method for doing so—and toexplain why it works.
On top of that, students are learning new strategies—even for basic arithmetic—that look foreign to many parents: What areopen number lines, decomposing and nets, and how do you multiply on a grid?
