  • Create a storyboard
    • See example of a visual storyboard on the next page.
    • Each sketch is a snapshot of a scene, known as a state in computer science.
    • It helps to use a template, see slides10 and 11.
    • If making a visual storyboard is too time consuming, the alternative is to make a textual storyboard, see slide 12.

  • Did you overlook any part of the story?
  • Is there something about the story that should be changed?
