My friend's kid asked me to explain what a 'for loop' does while we were waiting for pizza.

I told him it's like giving the same instruction to everyone in a line, one by one, and now I'm wondering if that's actually a good way to teach the concept to someone who's never seen code before.

That "line" idea is okay, but it misses the key part about doing something a set number of times. A real for loop is more like telling one person to take three steps, not telling three people to each take one step.

But what if you have three people? The line idea works for that case. It just depends on what you're trying to do.
