Answers on Overhead
After math quizzes or tests, I put the answers up on the overhead projector. Each student is to write a brief explanation of any problem missed. This is well worth the time involved for several reasons:
- If a student doesn’t know why he missed the problem, it prompts a question.
- If a student repeatedly writes the same explanation, it seems to have more of an effect than if I say the same thing.
- When I look over the papers, it saves me a great deal of time in evaluating missed answers.
- When the papers go home, it is immediately obvious to the parents the types of problems their students are having.
I learned this tip when working as part of the National Writing Project. It seems so simple, but changed my math teaching so much.
