Learning goals

  • Align two-digit addends vertically by place value (tens and ones)
  • Fluently add units digits and recognize when regrouping to tens is required
  • Accurately calculate the sum of two 2-digit numbers

Teaching and response guide

  1. Model the target skill: align two-digit addends vertically by place value (tens and ones). Use the first task as a guided example before asking for an independent response.
  2. Check readiness first: Add without regrouping and exchange ten ones for one ten.
  3. Discuss an incorrect response using this distinction: Carry one ten into the tens column rather than adding the written carry to the ones a second time.

Watch for: Carry one ten into the tens column rather than adding the written carry to the ones a second time.

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.
