That might be why it was added to the curriculum at first, but that's certainly not why it stayed, nor why we did it at my school. It's a pretty fun activity too, so a good use of that PE time.
I had horrible eyesight and was shockingly inept at all sportball games, even compared to other hopeless nerds, so I found it slightly less awful than the stuff we usually did.
I never had dancing in PE in any grade. Can’t decide if that sucks or not. Maybe I’d have better coordination now. We did get roller skating week though.
We did square dancing, but I'm from Texas, so our families joined the hoedown. I was so proud of my bolo, fond memories.
And I don't think it was part of the curriculum, I think they were just throwing a party for graduation or something. It's been years, and this was when I was little, in elementary school.
