So we made jump ropes out of used plastic bags. I made one beforehand and brought it outside before class started so the kids could get excited– they immediately used the jump rope as a limbo pole and then jumped over it (only a couple of them had ever used a jump rope in the way we typically do).
They dug it. I had about 70 kids in all, in three waves. It was hectic as all get-out but worth it, of course!
