Here's what the play is today. The big set of blocks I got here, but can also be purchased here. The book--which is very, very good--is here.
I have wanted a set of maple unit blocks since studying Early Child Education my first year in college, when the head of the department said, "If you have a budget which allows for only one thing, make sure that it is unit blocks." They are expensive, but the play value is endless. I'm so thankful that I could finally have them in my life.
