I will be using this to program differentiated worksheets for my math students. Each number (1-10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, & 1,000) is represented with base ten blocks in its own file. Both yellow and blue are available.
Hopefully you can use this to help students understand place value. I'm thinking this will help with common core standard 1.NBT.2 or 2.NBT.1, 2.NBT.7
