Scratch · Lesson 3
Motion and events
Making things move, and the event model that makes a program respond.
What you will cover
- Motion blocks: steps, turns, coordinates, and glide
- The coordinate plane — a natural bridge to grade-level math
- Event blocks: green flag, key press, sprite clicked
- Broadcast messages for sprite-to-sprite communication
- Why multiple scripts run at the same time, and what that means for debugging
