The pages in this packet were designed to supplement Chapter 2 of McGraww-Hill's My Math. It can also be used alone. I use these pages to break apart lesson 4.
There are practice pages (with step by step examples) on how to add using mental math of breaking numbers apart, rounding, and finding a ten.
There is a practice page with example and a story problem worksheet for each of the three mental math practices.
There is also a mixed review page as well as a quiz.
Thanks and keep checking back to my store as I add more supplemental packets and pages for my third grade My Math series!
