Ever want the kids to do their work, but have fun doing it? Play Jeopardy!

Pass out cards with numbers and colours on them to students. There are two teams, red and green. Call a number, and the two students with that number go up to the board. Ask a mathematical question, and have the students answer it. Do their 'working out' on the board.

When the first student's done, have them ring a bell. The first student to ring the bell, check their work. If they get it wrong, go to the other student, but if they get it right, give them 1 point.

At the end of the game, tally up all the points, and the team with the most points wins.
