Mustache Math

Rules

• Spread mustaches out on the floor in the front of the room.• Class divides into teams of 4 or 5. • A question appears on the screen and ALL students solve it

independently (unless the question says “team play”)• During a team play, all group members may collaborate. The

teacher will roll a die to pick a team.• A name is drawn at random. That student responds. If they get it

right, they come up and pick a mustache. They add/subtract that amount of centimeters to their team “stache.”

• “shave it for later” : team loses all points and start at 0

• Score is kept on the whiteboard.• No calculators until QUESTION 20

Expectations

• No talking while a question is on the board.• Conversation level of 1 during group

questions.• 3 strikes your out (back-up packets are already

on my desk).• Exhibit good sportsmanship.• HAVE FUN!
