Quick Tip
Add ones first (each sum < 10), then tens.
Teacher Resources
Teaching Notes

Emphasize lining up numbers by place value (ones under ones, tens under tens). Always start addition in the ones column, then move to the tens. No regrouping simplifies this foundational step.

Vocabulary
Regrouping: Exchanging tens for ones or vice versa.
No Regrouping: Sums in each column are 9 or less.
Common Mistakes
  • Not aligning numbers by place value correctly
  • Adding the tens column before the ones column
  • Mistaking which column is which (tens vs. ones)
Differentiation
SupportUse base-ten blocks or drawings to represent numbers and sums visually. Work with a place value mat. Start with adding a 2-digit and 1-digit number.
ChallengeChallenge with three 2-digit numbers to add (no carrying). Introduce estimation strategies for checking answers. Discuss mental math strategies for adding 2-digit numbers without carrying.
Discussion Questions
  • Why is it important to line up the numbers correctly?
  • Why do we start adding from the ones column?
  • What would happen if we added the tens column first?
Extension Activities
  • Add three 2-digit numbers.
  • Introduce simple regrouping.
  • Practice related subtraction.
