Review Detail

SM is the best math curriculum I've found. The lessons are engaging and they focus on multiple ways to approach a problem and with elementary math there is a bigger focus on mental math than I've seen in other curriculum. I love how the levels are broken into two books each. With the lesson book, the workbook, and the supplemental book you can buy, there is so much extra practice you never have to worry about hunting around on the web to find practice sheets that fit what you are working on.
