Number bonds practice worksheet for elementary math students.

The image shows a worksheet titled "Practice with Number Bonds!" from Math-Drills.com, designed to help students understand how numbers can be broken down into pairs that add up to a given total. This is a foundational concept in early math, particularly for addition and subtraction.

🔍 Understanding Number Bonds

A number bond shows the relationship between a whole number and its parts. For example, if the whole is 5, the parts could be 2 and 3 because 2 + 3 = 5.

Each problem on the worksheet has:
- A top number (the "whole")
- Two empty boxes below (the "parts")
- The goal is to fill in two numbers that add up to the top number

✔ Let's solve each problem:

We’ll find two numbers that add up to the top number. There are often multiple correct answers, but typically the problems expect basic combinations (e.g., using small whole numbers like 1–9).

---

#### 1.) 3
- Possible: 1 + 2 = 3 → 1, 2
- Or: 0 + 3 = 3 → 0, 3

But since it's likely targeting basic facts, let’s use 1 and 2

> ✔ 1 and 2

#### 2.) 3
Same as above → 1 and 2

> ✔ 1 and 2

#### 3.) 4
- 1 + 3 = 4 → 1, 3
- 2 + 2 = 4 → 2, 2

Let’s use 1 and 3

> ✔ 1 and 3

#### 4.) 4
Same → 1 and 3 or 2 and 2

> ✔ 2 and 2 (symmetric pair)

#### 5.) 5
- 2 + 3 = 5 → 2, 3
- 1 + 4 = 5 → 1, 4

Use 2 and 3

> ✔ 2 and 3

#### 6.) 5
Same → 2 and 3

> ✔ 2 and 3

#### 7.) 6
- 3 + 3 = 6 → 3, 3
- 2 + 4 = 6 → 2, 4

Use 3 and 3

> ✔ 3 and 3

#### 8.) 6
Use 2 and 4

> ✔ 2 and 4

#### 9.) 7
- 3 + 4 = 7 → 3, 4
- 2 + 5 = 7 → 2, 5

Use 3 and 4

> ✔ 3 and 4

#### 10.) 7
Use 2 and 5

> ✔ 2 and 5

#### 11.) 8
- 4 + 4 = 8 → 4, 4
- 3 + 5 = 8 → 3, 5

Use 4 and 4

> ✔ 4 and 4

#### 12.) 8
Use 3 and 5

> ✔ 3 and 5

#### 13.) 9
- 4 + 5 = 9 → 4, 5
- 3 + 6 = 9 → 3, 6

Use 4 and 5

> ✔ 4 and 5

#### 14.) 9
Use 3 and 6

> ✔ 3 and 6

#### 15.) 10
- 5 + 5 = 10 → 5, 5
- 4 + 6 = 10 → 4, 6

Use 5 and 5

> ✔ 5 and 5

#### 16.) 10
Use 4 and 6

> ✔ 4 and 6

| 5.) 5 | 2, 3 |
| 6.) 5 | 2, 3 |
| 7.) 6 | 3, 3 |
| 8.) 6 | 2, 4 |
| 9.) 7 | 3, 4 |
|10.) 7 | 2, 5 |
|11.) 8 | 4, 4 |
|12.) 8 | 3, 5 |
|13.) 9 | 4, 5 |
|14.) 9 | 3, 6 |
|15.)10 | 5, 5 |
|16.)10 | 4, 6 |

💡 Notes:

- These are not unique — many combinations work.
- Teachers may encourage different pairs to explore all possibilities.
- The goal is to build number sense and fluency with addition facts.
