This is an activity-based lesson on basic probability, chance, and operations including addition, multiplication, and equivalent fractions. It can be used with a wide variety of grade levels including elementary, middle, and high school as well as with adults. The game approach is one that students LOVE and can be revisited over and over in a scaffolded lesson design to build understanding of probability and chance. It does not require a lot of materials so it is low cost.
