Teacher Resources
Teaching Notes

Focus on place value and regrouping (carrying) from the ones to the tens column. Emphasize vertical alignment for accurate addition.

Vocabulary
Addend: A number added to another number.
Sum: The result when two or more numbers are added.
Regroup: To exchange groups of ten for one hundred, or vice versa.
Common Mistakes
  • Forgetting to carry over to the tens column
  • Incorrectly adding three single-digit numbers in the ones column
  • Misaligning numbers in columns
  • Adding the tens column before the ones column
Differentiation
SupportUse base-ten blocks or visual aids to model regrouping. Provide problems with smaller sums in the ones column.
ChallengeChallenge students to add four 2-digit numbers or solve multi-step word problems involving this skill.
Discussion Questions
  • Why do we start adding in the ones column?
  • What happens when the sum of the ones column is 10 or more?
  • How does knowing place value help us add these numbers?
Extension Activities
  • Use blocks to model addition.
  • Create your own addition problems.
  • Play addition board games.
Parent Tip

Have your child count out objects for each number, then count the total.
