This activity will only work if you have a gym with polished wood floors and some old blankets you dont mind wearing out a bit more (a few gunny sacks could also work). The game is simple. Divide your class into 2 or 3 teams. Give a clue to the teams and as soon as everyone has it on the team (teacher has to give the go ahead), then they can begin to race. That works by having one student be the rider (sitting down on the blanket) and one student being the horse (pulling the rider by holding an end of the blanket, or by pulling a rope that the rider is holding the other end of). At the far end of the gym (not too close to the wall) have cones or chairs set up that the chariots need to round before coming back. First team to return wins the points for that round.
