When is the last time you tried to do a jumping jack? I actually do them fairly frequently. My boxing instructor is a jovial sadist, and we do calisthenics until our arms hang like fresh pasta. I also do at least one jumping jack per year to introduce transitions to my students.
I the introductory transition lesson without an explanation of WHY. Instead, I walk in the room and immediately bark at the students to stack the chairs and push the desks against the walls. I then ask them to find some clear space where they won’t hit their neighbor if they fling their arms around. (I encourage them to fling their arms and test things out.) I then tell the class I will award prestigious prizes for the MOST CREATIVE JUMPING JACK, as judged by me.
SIDE NOTE: I keep a BAG ‘O MYSTERY filled with a few good prizes (mixed CDs I’ve made…toy light sabers…a Napolean Dynamite collapsible cup) and A LOT of obnoxious junk. I regularly comb thrift stores and garage sales and keep a strict nothing-over-a-dollar-rule. The kids (I’m talking juniors and seniors) go pretty crazy over this finely curated detritus. I always hype up the prestige of getting to pull from the BAG ‘O MYSTERY, and students usually take great pride in receiving the dorkiest of prizes. One student kept a chipped garden gnome in his locker throughout his entire high school career.
