Uno Stacko Final Exam Review

My brother in law gave me this idea. It is a uno-stacko review game. Uno-stacko is like Jenga. Here are the rules
1. Groups of 4.
2. Give a problem to the class.
3. Give time for them to solve the problem.
4. Call on someone at random.
5. If they talk you through the problem correctly, they pick two tiles.
If they don't get you through correctly, they pick four tiles.
6. If the tower falls when you are working on it, EVERYONE in the class gets extra credit, EXCEPT that persons GROUP of FOUR.
7. The students really get into it.
8. And yes, I have had students that want to knock it over and give the rest of the class extra credit. It never has happened yet.

Give it a try. Here is the video for it.

Pop Goes the Weasel and the Quadratic Formula

I thought I would show a video of a couple of students singing the quadratic formula to the tune of Pop Goes the Weasel. The students really like this. Give it a try.
