Teaching and response guide
- Begin with: Which planet is third from the Sun?
- Connect the response to: Order these planets from the Sun outward.
- Ask students to apply the idea: Which is farther outward in this order: Uranus or Neptune?
Watch for: Accepting an answer without checking whether it uses the material and satisfies the requested relationship or criteria.
Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
