This has been such a great toy/learning tool!
(don't you love when you can combine those two?!)
We got it for the boys this past Christmas and I really didn't think we'd get as much use out of it as we already have!
Caleb has gotten tons of use out of this.
He is learning patterns and counting and it's also a great activity to keep him busy (& relatively quiet!) while Sammy and I work on other things.
With Sammy we use them for addition and subtraction.
So absolutely worth the $ spent!
