This would make a great procedure (Harry Wong). Count to five or hold up one finger at a time when the class needs to refocus. Discuss what occurs for each number at the beginning of the school year and eventually the reaction will be automatic.
To make the Punch board, use Chinet styrofoam bowls, 2 layers of tissue paper, and tape. I taped the bowls to a science display board. Each student got to punch one, and inside they found candy and also a fun fact that we read to the class and discussed.
