Teaching and response guide
- Begin with: Write 406 in expanded form.
- Connect the response to: What is the value of 7 in 273?
- Ask students to apply the idea: How many tens have the same value as 3 hundreds?
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.
