In this interactive from APT, investigate the likelihood of a variety of chance events involving cards and spinners. In the accompanying classroom activity, students record how many times each of the numbers 1 through 8 comes up when they spin a spinner 80 times. They gain meaning for likelihood using experimental probability as they compare results with the theoretical probability of 1/8. They use the interactive and conclude by considering probability in everyday life. To get the most from the activity, students should be comfortable adding fractions with like denominator and finding equivalent fractions. This resource is part of the Math at the Core: Middle School Collection.
