This is a great game to explain to elementary students the difference between Aerobic and Anaerobic while keeping them moving!!!! I use these cards in my PE Scavenger Hunts. I hide them under cones and have the students race around to find them. Then they have to decide as a team if the card represents aerobic or anaerobic activities.
I also have used them in bowling units. If they get a strike/spare, they earn a card. First team to collect all cards and categorize them appropriately wins.
