My dd6 is having trouble understanding that, for example, 43 is larger than 21. For her facts, she is counting on her hands.
I actually called MUS today and spoke with someone for a while. I was really impressed. I ordered Gamma, Beta, and Alpha to take a look at. All of it. The teacher kit, student kit, and blocks. I might try it out, but keep going with CLE until I make a decision.
Did you switch from MUS to CLE?
