On the board there are stars with each child's name. When a child breaks a rule, a verbal warning is given and told what rule has been broken. The child is also told if he/she breaks the rule again, the star will drop. If the child breaks the rule again, the star drops for the day and doesn't earn a point that day. Hitting, kicking or biting another child is NOT accepted at school so that's an automatic loss of a child's star - NO WARNINGS!
On the wall next to the stars is a chart with all the children's names on it. This is how I keep track of the points the children accumulate and after earning 5 points the children get a trip to the Treasure Chest for one sticker! Then they start over earning their next 5 points again. This is done at the end of the day.
