Our school has standard based report cards for 2nd grade. With one of the standards, students need to be able to spell number words 1-100. I needed some sort of motivation for my students. So, I put each child's name on an ice-cream cone. I also had an ice-cream scoop to represent each math number word test. Every time the students passed a test, they got to put the scoop on top of their cone. That way everyone could see their progress. It made some work harder than usual because they looked at it as a race to the top!
