Student Self-Assessment Sheet
Give yourself a rating (see below) for each of the questions. Write some reasons why you gave yourself this rating.
The ratings are:
1 = Yes (I successfully did this.)
2 = I tried to do this and did a pretty good job, but I think I could do better.
3 = No (I did not do this successfully, I need to do more work.)
Now give your Student Self-Assessment Sheet to your teacher to talk about how you rated yourself.
Do they agree with your rating?
