My dd is driving me crazy!

Here I am going over her most recent math test and she made an 88%. I know she is very intelligent, but she just does the work and makes STUPID mistakes!! Yes, I said the word stupid, not to her of course. She has been reminded over and over and over to check over her tests before turning them in. Let me tell you about her most recent error. The instructions said to "Draw a circle and shade 25% of it". Simple, right??? Yes, it is simple unless you draw a rectangle!! What is she thinking???

But hey, her friend Lauren got it wrong by doing the same thing (excuse me she drew a square)~~that is what my dd said and I guess it was supposed to make me feel better?!?!

She made two other silly mistakes and we went over her test together--she knows it, but just doesn't pay close enough attention.
Well, this quarter, we will be playing hardball. It will be homework and studying for tests before ANYTHING else. Oh, my blood is boiling. She has always been so studious, but I do believe she is testing the waters. Wish us luck, because her grades WILL be improving.
