What do you do when an answer is wrong in your homework, or on a test? Do you throw it away and forget it-and then make the same mistake the next time? If you are wise, you will make those errors teach you something. Here’s what you can do:
1. Analyze the error to see if you can find what you did wrong.
2. If it is a careless error and you really knew how to do the work correctly, make a note of it, and if you find that you keep making careless errors frequently, start working more carefully.
3. If you can’t find where your error is, ask the teacher or a classmate to help you.
4. Keep a page in your notebook entitled, “Warning: Errors to Avoid.” On the same page write a description of the corrected way to do that kind of exercise, being sure to emphasize the important idea behind it.
