More information

Teach: rule, system, follow, decide, action. Use frames: 'If… then…'.

Use gestures or actions instead of writing.

Can students create and follow rules? Can they explain outcomes?

Fully unplugged.

Students may create unclear or conflicting rules.

Rule-based systems are used in programming, games, and decision-making systems.
