The team stop sign is a management tool that I created years ago help manage the noise level during cooperative learning activities. Print them out on card stock, cut out, and laminate. If a team becomes noisy or off-task, place a stop sign in the middle of the team. Ask team members to be quiet for one minute and think about how they can work more effectively and quietly. This strategy is simple, but it’s effective for bringing down the noise level in your room and helping your students to refocus on the assignment. They can also be used when doing math and literacy centers.
