I remember we had that turtle system (logo?) in third grade.

I never once realized I was programming! I thought it was just a dumb game to make a turtle move. And I remember always wishing I could learn how to program a computer at that age. If they had told me that's what I was doing I probably would have been more interested.

I guess the moral is to not abstract too much of the system from the child. Maybe they want to see variables, and print statements.
