This is a timed activity, with small groups of students creating math vocabulary graphic organizers. They will pass it around in their group and take turns filling out different corners until it is complete. The graphic organizer is the standard four-part model, with the vocabulary word in the middle: one corner is an example, one corner is an explanation, one corner is what it is NOT, and one corner is a picture. This can be adapted however you like.
-- Students form groups of four or less.
-- Each group is given a list of review math vocabulary words and a stack of letter-size paper (I often used scrap paper that had something printed on the other side).
-- Set the time for (about) 5 minutes.
1. Each student takes a piece of paper and folds it into quarters to divide into four parts and then unfolds it. Each student picks a different word from the list and writes the word in the middle of their paper, make sure to cross out the word they pick on the list.
2. When the timer is started, each student completes any one corner of their graphic organizer that they choose during the five minutes.
3. When the bell rings, they pass it to the left and the next person fills in a different corner.
4. When a paper is complete, they put it in their pile and start a new one.
It can be done for as long as you want, and also be a competition to see which group fills in the most. I grade them according to how accurate and thorough they were done, and also their conduct as I observed them.
