I have a fun activity for ya!
The materials: (per group of about 4) Ten plastic cups, three foot-long pieces of string, and a group of kids. I used seventh graders.
The rules: each player can only touch one end of one string. Only strings may touch the cups. No speaking or mouthing words (hand gestures are fine).
The tasks: first, move the ten cups from one desk to another across a span of about 3 feet. Second, stack the cups into a pyramid. Move the cups one by one back to the other desk without the pyramid falling. Last, flip the cups, and stack in a pyramid “mouth-up”.
My class LOVES this activity.
* note: the students in the picture played a slight variation. No, they’re not cheating.
