My second graders LOVED the obstacle course I set up in the gym as a math review for their chapter test. I split up my students up by their houses and each person took turns solving a math problem at each station before completing the task. The first round was practicing their basic addition and subtraction facts. Second round was subtracting three-digit numbers with and without regrouping. I had extra hands help with sanitizing and resetting each station after each person completed it. IT WAS SO FUN!!
