Want to win a TNT? Then start teaching your friends

1. In your group of 5, you must watch each video in the order listed below.
2. You must watch the entire video regardless whether you know it or not.
3. After each video, you must ask other members in your group 'Did you get it completely?" Write an example of how to do it in your book. Each person in the group needs to do this.
4. If anyone is unsure, it is the responsibility of those students who have understood to teach those who do not understand. My suggestion, provide examples and get those people to practice.
5. Only after everyone has understood the strategy are you allowed to move forward and watch another video.
6. After you have watched all 9 videos and have understood it (all group members), you may start making your poster (see diagram below). Every student will need to learn and understand each strategy. You will use the numbers above and use each strategy to solve it. You need to show all working out with explanations.
7. To win the TNT, it is not about who finishes first. The teachers will ask random groups to present and random students to present within that group. If the student chosen cannot explain how to do a strategy, the group as a whole will not win the TNT.
