I use this as a classwork or homework assignment. It is a quick review which shouldn't take the students too long. It can be used as independent, partner or group work. IN order to make it take a whole class period. I usually give each student one term and have them walk around the class and each time they pick a new partner they must tell each other which term they have until they have 15 different terms. At each partner they discuss where they think each of their answers should go. It is a fun interactive kinesthetic activity where students get to get up and out of their seats and engage in academic discussion.
