These "Caught Showing Great Character" cards are used in my classroom by the students. When they witness another student showing one of the character traits, they grab one of these cards and fill it out by telling who they "caught" and what they did. We begin each day reading the cards out loud and cheering for each other. It is one way that we encourage daily bucket filling!
This focus on the positive has always brought a great atmosphere to the classroom and encourages positive behavior from everyone in the class -- they ALL want to get "caught"!
