A simple teaching strategy

This used to be such a common teaching practice but I don't see it much any more. It certainly is a NOISY activity but if you value sharing and discussing of ideas, this is the strategy to use.
THINK - PAIR - SHARE can be used with just about every classroom activity.
The principle is simple
1. Individually a student works on an activity.
2. The student then PAIRS with ONE other student and together they discuss the activity.
3. THE PAIR then joins with another group (can be just another pair) and SHARES the activity again.

This could be used in any subject area.
