Ratio and Proportion online games

http://www.4kids.org/games/ has a couple of ratio and proportion games (specifically Ratio Stadium and Dirt Bike Proportions). They are multi-player games that look very simple to set up for four students to play against each other. The would be good for just a ten-minute filler; the numbers are very small and meant for younger kids, but it might be a fun way to start class before diving into “If You Hopped Like a Frog”.
