Roundtable Review (for previous day's TED) With this activity, I have students get out a sheet of paper and write a list of numbers from one to 10. Then I instruct them to put one important idea from the previous lecture on the first line. The paper is passed to the person on the left. Each time the paper is passed, the person receiving the paper writes a different idea. After a few minutes I call time, and the papers go back to the original owner. This makes a nice collection of ideas for future review and study.
