5 – Round and Round

🎯 Learning Objectives

  • Use iteration (while loops) to control the flow of program execution
  • Use variables as counters in iterative programs

💬 Key Vocabulary

  • Iteration
  • selection
  • counting
  • execution
  • walk-through
  • conditions

📖 Iteration

  • When your programs repeat actions, checking for a terminating condition at the beginning of each new loop this is called a while loop.
  • You will need a while statement: when your program needs to repeat actions while a condition is satisfied.

In this lesson, you…

  • Used iteration (while statements) to allow the flow of program execution to include loops
  • Used variables as counters

Next lesson, you will…

  • Apply what you’ve learnt and use iteration even more!
  • Take a quiz, to assess what you’ve learnt
