Organize: 3 mins

 Form teams of two

Learn Scratch: 15 mins

Elicit and Document Requirements: 15 mins

 You may determine the requirements for your project, but it must meet the following:
  1. Create either a story animation or a game
  2. Require the user to provide input (click or keyboard)
  3. Must have at least one loop
  4. Must use at least two costumes for a sprite
  5. Must track something through a variable

Document your requirements in user stories on 4x6 cards. Here are some sample user stories:
Title Description
Pop Bubble User moves mouse over a bubble that has not been popped and clicks. Bubble pops. Score increments by one.
Pop Bubble with Bomb User moves mouse over a bubble that has not been popped and clicks. Bubble pops and bomb explodes, ending game.

Create a rough sketch of one or two scenes to explore and communicate the idea of how your system will look.

Design: 15 mins

 Give each pair a blank piece of paper. Create storyboards: draw up to eight frames per page, fill with scenes

Construct: 30 mins

 Create your system.

Test: 8 mins

Swap computers with another team. Test their system and record any defects you find on 4x6 cards. A defect report should contain the following information:

  1. Defect number (make sure they are unique starting with 1)
  2. Short title
  3. Description of defect (what went wrong?)
  4. Description of what happened before defect occured (what were you doing?)

Fix: 8 mins

 Return computers and defect reports to original team. Review and fix the defects. Ask clarifying questions if needed.
