**Math Survivor!** Which team will be eliminated first? Which team can survive?

After reading about Grudgeball on Elissa’s site and then here, I couldn’t wait to try it. I decided to call it * Math Survivor *since we were “voting teams out of the competition”, and I didn’t have them shoot a nerf ball. I’m glad I eliminated the nerf ball, because the voting people off took forever by itself!

I love jumping right in and trying new things. However, sometimes this means I fail. And fail I did at first! I must have misread the instructions. I thought that ALL teams got to erase x’s each time. That made sense to me, as why else would they work hard to get the question correct? However, it became obvious during my first class, when ALL teams were quickly eliminated, that my game had a flaw. I adjusted it for the next class, letting them add points back more easily, but then everyone was just tied. Finally, for my third class, I decided to let only one team at a time take off x’s. DUH. To keep kids active, I told them that if the team voting x’s off missed the question, I would roll dice to see which team got to take their turn. This keep everyone motivated for every question.

The game I made is for Piecewise Functions and Transformations, but I also made a blank template. Here are my rules, templates are below.

**Goal:** To be the last team standing (still have x’s)

**Rules:**

- Every team starts with 10 x’s.
- Every team works on every question. Only one team at a time gets to eliminate x’s for each question. I just rotated around the room.
- One team at a time gets to erase 2 x’s, if they get the question correct. They can erase 2 x’s from one team, or erase one x from two teams. They cannot commit suicide (erase their own x’s).
- If the designated team misses the question, then another team gets to erase the two x’s. I rolled dice to decide which team. You could also pick popsicle sticks.
- Once a team is eliminated, they cannot add x’s back, but they can still vote other teams out! (
*Some teachers let teams add points back or eliminate x’s*). - I let kids make alliances. It almost never works out! Just like in the real Survivor, alliances quickly crumble. lol!
Only let one person per group erase and make them decide BEFORE coming up to the board who they are going to eliminate. Otherwise, peers from the other teams can influence them once they are at the board. I even do a 5, 4, 3, 2, 1… count down. You can also ask them (have them write it on a white board, and erase the x’s yourself if you have a very enthusiastic or overly competitive class).**TIP:**

Blank Template and Piecewise Functions and Transformations Template.

*Update:* Thanks to the Twittersphere, I had some great feedback from Bowen Kerins!
