Teaching and response guide
- Model the target skill: add and subtract fractions with unlike denominators. Use the first task as a guided example before asking for an independent response.
- Check readiness first: Recognize equal parts of one whole.
- Discuss an incorrect response using this distinction: The denominator counts all equal parts. For addition, establish a common denominator rather than adding denominators.
Watch for: The denominator counts all equal parts. For addition, establish a common denominator rather than adding denominators.
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.
