For me, at least, the way I exercise my programming skills is on my TI-83+ calculator.
After learning the commands which are similar to c but easier to use, I have made a lot of fun projects. My favorite was a sudoku program.
Plus, a benefit of calculator programming is that you can do it all math class long, and the teacher will never notice.
