HM Math By Amanda K.

I really like the version we have. It's easy to use, it teaches higher level thinking, and there's plenty of review of previous concepts. There's also a lot of supplementary materials, including practice books, challenge books, and reteach books. You can also print out homework pages from HM online. The teachers in my district also got to choose one extra item, and we chose the first grade Math Centers kit, which has center activities for each lesson taught. It's really awesome. I'll be keeping that even after we have another adoption.
