Math Block Manipulatives (Place Value Blocks)

My wife is teaching our sons math and wanted some manipulatives to teach the place values. So, I whipped these up for her real fast, as a way for them to physically interact with the 1s, 10s, and 100s spots and better grasp their meaning. Anyway, because we live in the future, I was able to crank out a bunch of these over a few days and now the kids have a new learning tool!
