🔎 Summit: Must Be & Can't Be
The studio door is unlocked, the tea is still warm, and nothing is missing — someone must be near. Students learn to make near-certain deductions with must be, rule out impossible ideas with can’t be, and tie every deduction to evidence with because. They finish by writing a 50–80-word case report about a scene of their own.
Lesson Plan
- Four quick detective scenes to read and discuss
- Say what you know for sure — before any grammar
Key Vocabulary
Grammar Points
