Can you draw a perfect circle?
I know that I couldn't, but with help from a SmartBoard game it became easier and my students loved to draw circles on the Smartboard for a great end of the year activity.
I had students put their name with their high score and by the end of the day we had a leaderboard and by the second day students were inching closer to my high score. (Yes, I did practice for 2 hours to beat some of my students.)
It was a great competition to get students engaged and motivated in the classroom. I hate to see teachers only using a SmartBoard as a presentation tool, it is there for students to use and manipulate. I had some students up there for 20 minutes trying to get the tips and tricks down and finally making the leaderboard.

Some of my students didn't know what the cat was there for, but it is a great reminder to tell the students how close they are to 100% like a badge. If the students do poor enough, they get an angry cat that all the students laughed at.
