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 0Score is kept on the whiteboard.No calculators until QUESTION 20Slide3

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!Slide4
