Module 5: Decomposition by Sequence

Decomposing a Sequence of Events

Theme: Sports

Purpose: Students will learn to decompose a sequence of events by using interdependencies of sprites to perform an action until certain sensory conditions are met.

Lesson Goals:  I can...

  • Decompose a sequence of events based on actions and events.
  • Identify the Scratch conditions that properly start and stop actions.

Activity 1: Soccer

Decomposing an animation into a sequence of events using a timeline graphic organizer and identifying what signals shift between elements of the sequence.

Using … until blocks to implement multi-sprite sequential events:

Activity 2: Animating a Scenario

Students will select a scenario of their choice, use a decomposition timeline to plan the action within the scenario, and animate it using sprites and backdrops of their choice.
