How can this be math?
The children aren't sitting at tables with their math books? It looks more like movement activity?
It is actually both math [logic], and dance.
It is a logic activity created by Jesse.
Jesse wrote down instructions on slips of paper and each child was given a note with their personal instructions. As examples each note included a different instruction such as "Dance" "Hug people", "If someone touches you, fall down", "If and only if someone touches you, jump."
The children read their slips, and performed the action until Jesse said, "stop".
The audience had to guess what the "dancers" were doing.
You could see the wheels turning in their brains as they analyzed the "dance" trying to determine what each slip of paper may have said.
