Shout out to Patricio, who came up with the idea for this game.

We are currently doing a little geometry mini-unit in 8th grade, and one of my students had this idea for a vocab game. We ran it today, and it rules.

It’s “Simon Says” but with some geometry themed prompts. Some of the ones that we used today were as follows:

“Segment says: Make a line” (lines continue forever in both directions, so students point with their fingers)

“Segment says: Make your line steeper.”

“Segment says: Make a line segment” (line segments terminate at both ends, so students ball up their fists)

“Segment says: Make a ray that points to the door” (One hand pointing, one hand is a fist)

“Segment says: Make a 90 degree angle”

“Segment says: Make a line with a slope of zero” (undefined works great too.)

“Segment says: Find a friend and make supplementary angles.”

“Make an obtuse angle.”

You’re out! I didn’t say “Segment says!”
