Teaching and response guide
- Begin with: Find y when x = -3 for y = x².
- Connect the response to: For y = x² + 2, find y when x = 0.
- Ask students to apply the idea: Plot the five table points and connect them with a smooth curve.
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.
