Design an investigation

Target: Choose a plan that has a question, a measure, and a display.

Language target: Order the plan: question, measure, display.

Likely miss: Students collect data before naming the question.

Ask: What will you record for each person?

If you see it: The question decides the variable and the display.

Evidence to listen for: The plan names the question, the measure, and the display.

Next: If the display comes first, ask what question it can answer.

Observable student moves: names both quantities, uses the represented relationship, and revises after feedback. This companion is not a score.
