A cool game idea S and I just developed for either 1 or 2 players:

Each team is given a 4-quadrant grid with several enemy ships positioned at different locations around the origin (the Death Star). Before the student can shoot the Death Star, he and his partner must take out all of the opposing fighters. Each student takes turns rolling two different-colored dice. These are their two coordinates. The student then spins a spinner to find out which quadrant their point is in. The student then selects a fighter to shoot and determines the equation of the line from his point to that fighter. The students take turns blowing up the fighters. If a student’s coordinate lands on a fighter, he loses his turn. When all of the fighters have been eliminated, the students can roll one more time to blow up the Death Star.
