Ask students “Do we need a loop here?” to help them determine the appropriate loop to use without having to know the proper syntax to write that loop.

  • When teaching students how to use loops, ask them:
    • Where do we need a loop?
    • Why do we need a loop there?
    • How do we write that loop?
  • The following loops are important in AP CS A and require a lot of specific syntax:
    • while
    • do-while loops
    • for
    • for-each loops
  • Note from the CS Teaching Tips Team: Send students struggling with loops to CodingBat for more practice!
