Rate Tips

Assign students to draw a dodecagon in Scratch before introducing repeat blocks so that once you introduce the repeat block, it is clear that it is a time-saving block.

  • The repetitive nature of this task creates a pain point to motivate the need for repeat blocks.
    • Use student complaints about the task to begin your introduction of the repeat block.
    • This pain point will demonstrate the usefulness of the repeat block and increase students’ learning and retention as students are more likely to remember a concept when it solves their problems.
  • Use this same strategy to motivate functions, classes, etc. When you use this strategy, a new concept becomes useful to the student rather than just another thing they have to learn.
