Great Test or Quiz Review.
Purchase the individual snack pack sized jelly bean packages for each member of your class (or get large bags and scoop into dixie cups for each student). Have students pull out a blank piece of paper to show all work. Project the last slide in this PowerPoint onto the screen and have each student work out one problem for each jelly bean they received. One red jelly bean = one red problem. Three yellow jelly beans = three yellow problems.
