trying to remember how to play “school”. i know 3rd grade we jumped in from the back side. one of the grades we had to run through. one was jumping on one foot. 11 and 12th it seems we started out doing blue bells or someting and then they twirled as fast as they could and we jumped to 12 and had to get back out to finish. all the kids in out nieghborhood played this game, it was a blast and i wanted to teach it to my kids.
