In this lesson, pupils will work with count-controlled loops in a range of contexts. First, they will think about a real-life example, then they will move on to using count-controlled loops in regular 2D shapes. They will trace code to predict which shapes will be drawn, and they will modify existing code by changing values within the code snippet.

Learning objectives

  • To modify a count-controlled loop to produce a given outcome
  • I can identify the effect of changing the number of times a task is repeated
  • I can predict the outcome of a program containing a count-controlled loop
  • I can choose which values to change in a loop
