You’re working on a
2-Digit Addition worksheet that asks you to
draw tens and ones to help solve each problem. This is a great visual strategy for understanding place value and how addition works.
Let’s solve each problem step-by-step, and I’ll explain how to draw the tens and ones for each.
---
🔢 Problem 1: 43 + 24 = ?
-
Break down the numbers:
- 43 = 4 tens + 3 ones
- 24 = 2 tens + 4 ones
-
Draw it:
- Draw 4 long rectangles (tens) and 3 small squares (ones) for 43.
- Draw 2 long rectangles and 4 small squares for 24.
-
Add them together:
- Tens: 4 + 2 =
6 tens
- Ones: 3 + 4 =
7 ones
- Total:
67
✔ Answer: 67

🔢 Problem 2: 65 + 12 = ?
-
Break down:
- 65 = 6 tens + 5 ones
- 12 = 1 ten + 2 ones
-
Draw:
- 6 tens and 5 ones for 65.
- 1 ten and 2 ones for 12.
-
Add:
- Tens: 6 + 1 =
7 tens
- Ones: 5 + 2 =
7 ones
- Total:
77
✔ Answer: 77

🔢 Problem 3: 36 + 33 = ?
-
Break down:
- 36 = 3 tens + 6 ones
- 33 = 3 tens + 3 ones
-
Draw:
- 3 tens and 6 ones for 36.
- 3 tens and 3 ones for 33.
-
Add:
- Tens: 3 + 3 =
6 tens
- Ones: 6 + 3 =
9 ones
- Total:
69
✔ Answer: 69

🔢 Problem 4: 45 + 30 = ?
-
Break down:
- 45 = 4 tens + 5 ones
- 30 = 3 tens + 0 ones
-
Draw:
- 4 tens and 5 ones for 45.
- 3 tens and no ones for 30.
-
Add:
- Tens: 4 + 3 =
7 tens
- Ones: 5 + 0 =
5 ones
- Total:
75
✔ Answer: 75

🔢 Problem 5: 28 + 51 = ?
-
Break down:
- 28 = 2 tens + 8 ones
- 51 = 5 tens + 1 one
-
Draw:
- 2 tens and 8 ones for 28.
- 5 tens and 1 one for 51.
-
Add:
- Tens: 2 + 5 =
7 tens
- Ones: 8 + 1 =
9 ones
- Total:
79
✔ Answer: 79

🔢 Problem 6: 52 + 14 = ?
-
Break down:
- 52 = 5 tens + 2 ones
- 14 = 1 ten + 4 ones
-
Draw:
- 5 tens and 2 ones for 52.
- 1 ten and 4 ones for 14.
-
Add:
- Tens: 5 + 1 =
6 tens
- Ones: 2 + 4 =
6 ones
- Total:
66
✔ Answer: 66

## ✍️ How to Fill Out the Worksheet:
For each box:
1.
Draw the tens (long rectangles) and
ones (small squares) for both numbers.
2.
Count the total tens and ones after combining.
3.
Write the sum in the box.
Example for 43 + 24:
```
[||||] [|||] ← 43 (4 tens, 3 ones)
[||] [||||] ← 24 (2 tens, 4 ones)
---------------
[||||||] [|||||||] → 6 tens, 7 ones = 67
```
