Teaching and response guide
- Begin with: There are 12 apples. Five are eaten. How many remain?
- Connect the response to: Nia has 11 stickers. Leo has 7. How many more does Nia have?
- Ask students to apply the idea: Draw a model for 10 - 3.
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.
