Well, I have to add to the previous post. I am proud of myself!
Isaac did not do well on a math test. For homework he had to correct his errors, explain where he made his mistakes and give the correct answer.
As I was making dinner he was sitting at the kitchen table struggling. So when dinner was done I asked him to show me his test and explain the missed problems to me.
Now, I have no idea how to do these pre-algebra problems, and negative numbers have never made any sense to me. But after discussing each problem, including allowing ourselves to say "when would I even need this?!", we worked through them, and with Isaac's knowledge of the "rules" and my problem solving skills and logic, we did it.
I think Isaac feels better, and I am right proud of myself!
