You're working on a
2nd-grade addition worksheet that teaches
adding two-digit numbers with regrouping (carrying) using
place value columns (Tens and Ones).
The directions tell you:
> *Add the numbers in the ones column. Write the number of tens in the box, then write the number of ones under the ones column. Add the numbers in the tens column, including the number in the box. Write the answer.*
This is teaching
regrouping: when the sum in the ones place is 10 or more, you “carry” the extra ten(s) to the tens column.

Let’s solve each problem step by step.

1 in the box (that’s 1 ten to carry over).
-
Tens column: 1 (from 16) + 5 (from 54) + 1 (carried) =
7

## 📝 Teaching Tip:
This worksheet reinforces
place value understanding and
regrouping — foundational for multi-digit arithmetic. The “box” is where students record the
carry-over (the extra ten(s) from the ones column). Always add the carried digit to the tens column!
Let me know if you’d like this turned into a printable answer key or need visual diagrams!
