Piece of trash
It’s a horrible piece of trash
Don't waste your money
I wanted the ability to use the Base 10 blocks to work subtraction with regrouping. There's no undo button if they make a mistake placing blocks. If you use the pencil, I haven't found a way to turn it back off. When you move a ten stick to the ones place, there's no way to break it apart into ones. Number sense is much easier to use and it's free.
