Quick Tip
Teacher Resources
Teaching Notes
Emphasize aligning numbers by place value (ones under ones, tens under tens). Begin by adding the ones column, then move to the tens column. Introduce regrouping when the sum of the ones column is 10 or more.
Vocabulary
Common Mistakes
- Misaligning digits by place value (e.g., placing the 1-digit number under the tens place of the 2-digit number).
- Forgetting to regroup when the sum of the ones column is 10 or greater.
- Basic addition errors within each column.
Differentiation
Discussion Questions
- Why is it important to line up the numbers by their place value when we add in columns?
- What happens if the numbers in the ones column add up to 10 or more? What do we do?
- How is adding in columns similar to or different from adding numbers mentally?
Extension Activities
- Add 3-digit and 1-digit.
- Add 2-digit and 2-digit.

Parent Tip
Use small objects to represent tens and ones for addition practice.
