This is a freebie that's offered in lots of different versions to hopefully meet your classroom theme!
The idea is basic but one that's very effective in class! Simply split your class into teams. It can be the groups they sit in or grouped by numbers, etc. Print and laminate the style you like! This freebie has each style featured for teams of FOUR or teams of SIX.
Each time the team is exhibiting a GOOD behavior and setting a great example, give them a tally point in their team box. Total up the points at the end of the week, or every two weeks, or however often works best for you and your class. Then, reward the winning team with a prize such as lunch with the teacher, treasure box, etc.
I hope you enjoy it!
