This is a great way to get the entire class involved in the learning process, what most would call cooperative learning. If you are unfamiliar with the Kagan strategy of Quiz, Quiz, Trade, I will give you a brief rundown. Each student is given a card with a problem on the front and answer on the back. When the teacher gives the signal, students put their hands up and walk around until they match up with someone. They face each other holding their questions so the other can see it. One at a time, they try to answer the question contained on their partner’s card giving positive reinforcement after the correct answer is given. Once both have answered correctly, they trade cards, a hand goes up and they walk around to pair up with someone new. The process repeats as long as you feel necessary.
These are simple cards, yet very powerful and helpful when trying to understand the basic concept. Strategically made so all you need to do is print (preferably on card stock), fold the paper in half, cut them up and laminate them for durability (not necessary, but recommended). Hand one out to each student and off they go. I prefer to do this activity to reinforce a basic skill that we have gone over plus it gets the students out of their seats and talking to other studetns. I take a card myself and go around quizzing students as well. You can use them however you deem necessary.
Cards consist of 40 inequalities.
