Careless mistakes on tests and homework are about to drive me insane. Notice I said careless mistakes. Example: You ask your child what it means to give off heat and he answers "radiate."
He knew it before the test, and after the test, but not during the test.
The one bright spot in all this frustration is that mom showed me some of my papers she had come across from when I was in elementary school. Boy, did I turn out just fine inspite of that work. I couldn't write well, nor could I do the math.
It gives me hope.
