We have the manipulatives and I try everyday to use them. But she doesn't get it. I know I'm doing a bad job of explaining. But, for example, in MUS when they add 9+x. They teach to take one from the number that is being added to make a 10. Then add !0+ whatever is left. She can see it with the blocks but she is not making a connection. Should I just have her use the 9 block + the x block and count the total? I'm just scared to move on if she's not getting it.
