A great review learning activity is to have students divide a piece of paper into 4 quadrants. Then they wad the paper up and throw it on the floor. Each student now grabs another piece of paper and repeats the activity, writing in another quadrant. Students can't write something that they already wrote OR repeat something already on the sheet. After repeating this activity four times, I chose one student to read something from her sheet. That student chooses another student, who has to explain/perform/demonstrate the one thing the previous student read as well as something from his sheet. We keep repeating until all students have been called on. This is a great way to review and have fun.
