Teaching guide, sample answers and curriculum references
Before you begin
Add without regrouping and exchange ten ones for one ten.
How to use this worksheet
- 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.
- Check readiness first: Add without regrouping and exchange ten ones for one ten.
- 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.
A common mistake to discuss
Carry one ten into the tens column rather than adding the written carry to the ones a second time.
What to practice next
Show a carried ten with a place-value drawing for one equation.
Example: 47 + 28 = 75.
What is regrouping in second grade addition?
Regrouping (also known as carrying) is the process of making groups of tens when adding. When the ones place sum equals 10 or more, ten ones are regrouped into one ten.
Does this worksheet include an answer key?
