I use this to teach different prefixes and then I hang them up in our room as the students memorize them.
First, we talk about each one. I then have them get with a partner and they get to come up and choose one prefix sheet to complete. In the center they draw a picture to describe the prefix. After they have finished drawing, the papers are put on the board. After everyone is done, I call them one at a time to come up and explain to the class why they drew what they did and how it depicts the prefix.
There are three different sets included in the download.
