This is a great book for explaining some of the steps children should go through while constructing and understanding of multiplication and division. I read this in the summer, and it fueled a lot of ideas for the school year's instruction. It also contains several minilesson ideas throughout, which I had intended to put to use, but never ended up doing so. Still, I highly recommend it as a book that helps teachers set a strong focus for the year's math instruction.

This book continues the excellent work described in YMAW: Connecting Number Sense, Addition, and Subtraction. The problems described may at first glance sound similar to those in classrooms across North America, but the ways the teachers take these problems up with their students transforms them into very meaningful contexts that go much deeper than the supposedly "simple basics" they are often reduced to. By approaching multiplication and division in the ways described here, students will have a strong foundation for understanding ratio and fractions and for working with algebra.
