Teaching and response guide
- Model the target skill: identify when borrowing from the tens place is necessary. Use the first task as a guided example before asking for an independent response.
- Check readiness first: Subtract single-digit quantities and understand tens and ones.
- Discuss an incorrect response using this distinction: After renaming one ten as ten ones, reduce the tens digit; do not leave both digits unchanged.
Watch for: After renaming one ten as ten ones, reduce the tens digit; do not leave both digits unchanged.
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.
