Our school uses Leader in Me with our kids. I created these as a way to acknowledge the students who are using their 7 habits. I laminated these and hole punched the top and have them hanging on lanyards.
When someone has demonstrated one of the 7 habits, they get to wear the lanyard around school for the day. At the end of the day, they return the lanyard to me and they get a little certificate to take home.
Another option is to just print these cards out and hand them out to students when you catch them being a leader.
I used a Mickey/Disney theme to match my classroom.
