Wordsplash

"Splash" terms all over a sheet, and have students make relationships between the terms. I usually have students write out a couple sentences on the board using as many terms as they can.

Usually, descriptions of this call for a "predictive" phase before you study, then students check on their predictions. However, I've used it simply as a summing up tool after studying material.

It works effectively both for reviewing specific terms, and for getting students to think about relationships, i.e., go beyond recall.
