Cards consist of 36 triangles with a missing angle. Students try to figure out the missing angle. 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 or reinforce a basic concept. All you have to do is print them out preferably on cardstock. Fold the sheet in half so the questions and answers end up front and back. Cut them out, laminate for durability is what I recommend, hand one out to each student and off they go. Great 10-15 minute review for the students on a basic skill.
