Loops & Repetition

Summary

This chapter introduces loops as a way to repeat blocks efficiently, covering fixed-count loops, condition-based loops, and the forever loop, along with loop counters, nested loops, and how a loop body executes. Students also learn about loop efficiency and the risks of an infinite loop. This chapter is deliberately taught before the drawing chapter that follows, since drawing polygons, stars, and spirals depends on understanding repetition first, and it builds on the scripting foundation from Chapters 2 and 3. After completing this chapter, students will be able to write and nest loops to repeat actions a fixed or condition-based number of times.
