While Challenge was out this past week, we created a pretty fun probability game. A student puts 10 unifix cubes into a paper bag (any combination of colors and amounts). Another student then pulls out one cube at a time and records the results. After 50 or so "pulls" the student then makes an inference as to how many of each color are in the bag. This game took lots of inferencing - you really had to study your results. We learned that the more "pulls" you make, the more likely you are to have accurate results. With more accurate results, you're able to make a better inference of what's in the bag. Here are some pictures of our kids at work...
