Computer programming teachers often say, “Iteration is repetition. Iteration is repetition. Iteration is repetition.” You get the point. To repeat is to iterate. To iterate is to repeat. We often call it a loop or looping.

Example: Walking. We don’t think much about it, but our bodies repeat the same sequence of actions whenever we walk. The basic visible action of walking breaks down to repeating the actions ‘left foot forward’, ‘right foot forward’. A school day often repeats a similar sequence of events.
