Teaching and response guide
- Begin with: What is intentionally changed?
- Connect the response to: Name two conditions kept the same.
- Ask students to apply the idea: Would using heavier blocks for only one fold keep the comparison fair?
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.
