Grudge ball: End of Level Review

Instructions

What I did for grudge ball was divide the class into 5 groups (it’s harder and takes longer if there are more groups).

Each team starts with 10 X’s on the whiteboard—the goal is to have the most X’s at the end of the game.

The questions rotate around the room to the different teams.

If the team gets the answer wrong, another team gets the chance to steal the points.

If the team gets the answer correct, they get to erase 2 X’s from any other team or add 2 X’s to their team. (They can’t erase X’s from themselves). If they answer the question correctly, a person from the group gets to short the nerf ball from either a 2-point line or a 3-point line. If they make the shot, they get to erase 4 or 5 X’s (If they miss it, they still get to erase 2).

If a team loses all of their X’s, they can add X’s back to their team when they answer a question/make a basket.
