It's like Battleship, except you use parabolas, lines, and unit circles (for advanced classes).

Divide the class into 2 sides. Take the first 3 students in a row and make them a team. Do the same with the other side. Repeat for each turn.

Have a x-y axis transparency on the projector, [-10,10] on each axis. Ask each team to write down where they will place their graph. It can be a line, a parabola, or whatever. Draw one side's graph, then the other.

If the 2nd team's graph intersects the 1st's, they get a point for each intersection. They then need to find the points of intersection and hand them in. While they are doing that, have the next team go. The next time, the other team goes first.

"You sunk my parabola!" (God I'm such a dork. :)

I would write more about the fine points and rules, but owwwwwwwwwww.
