Here’s a great management technique from Mr. Anthony Ness at Belleview Middle School in Belleview, Florida.
When students are working in cooperative groups, give each group a red, yellow and green paper cup in a stack. Each group keeps the stack of cups face down on the table. If the group is still working then they keep the red cup on top. This lets the teacher know, “Not ready to stop because we are still working”. If they need assistance then they put the yellow cup on top of the stack. Once the group is finished and ready to move on, they place the green cup on top of the stack.
This easy technique allows you the teacher to continuously survey your students and where they are during the assignment.
