"Integers Up!" is a great way to tie together many of the concepts students have mastered from adding, subtracting, and multiplying integers to percents and discounts. This game is extremely versatile in that it can be used for individuals, group settings, or with the class as a whole. Students have a blast with one another as they joke about each other's earnings and losts. Use this fun activity as a class activity, test prep, or end of year review. Either way, students will be glad you did!
