Plan a discovery
Target: Plan a small investigation with a question, a measure, and a display.
Language target: State the plan in three ordered steps.
Likely miss: Students choose a task that sounds interesting but cannot be checked.
Ask: What will you measure, and how will you show it?
If you see it: Ask what someone could measure or point to.
Evidence to listen for: The student selects a plan that can be tested.
Next: If the class likes a vague idea, help them rewrite it into a measurable question.
Observable student moves: names both quantities, uses the represented relationship, and revises after feedback. This companion is not a score.
