Number Bonds worksheet for practicing addition with visual number bond diagrams.

Let's solve the Number Bonds worksheet step by step.

🔷 What are Number Bonds?

Number bonds show how numbers can be split into two parts that add up to a whole. For example, the number bond of 5 could be 2 and 3 because $2 + 3 = 5$.

We need to fill in three unique pairs for each total (5, 6, and 7), where the two smaller numbers add up to the top number.

✔ Problem 1: Write any 3 unique number bonds of 5

We need three pairs of numbers that add to 5:

- $0 + 5 = 5$
- $1 + 4 = 5$
- $2 + 3 = 5$

> These are all unique and valid.

So, we can fill in:
```
5 5 5
/ \ / \ / \
0 5 1 4 2 3
```

✔ Any combination like this is acceptable.

✔ Problem 2: Write any 3 unique number bonds of 6

Find three different pairs that add to 6:

- $0 + 6 = 6$
- $1 + 5 = 6$
- $2 + 4 = 6$

(We skip $3 + 3$ if you want strictly different numbers, but it's still valid. However, since they ask for "unique" bonds, using $3+3$ is okay as long as it's not repeated.)

But let’s pick three distinct pairs:

- $1 + 5 = 6$
- $2 + 4 = 6$
- $3 + 3 = 6$

Or alternatively:
- $0 + 6 = 6$
- $1 + 5 = 6$
- $2 + 4 = 6$

Either way works.

Let’s go with:
```
6 6 6
/ \ / \ / \
1 5 2 4 3 3
```

✔ All add to 6 and are unique combinations.

---

✔ Problem 3: Write any 3 unique number bonds of 7

Now find three pairs that add to 7:

- $0 + 7 = 7$
- $1 + 6 = 7$
- $2 + 5 = 7$
- $3 + 4 = 7$

Choose any three:

Let’s use:
- $1 + 6 = 7$
- $2 + 5 = 7$
- $3 + 4 = 7$

So:
```
7 7 7
/ \ / \ / \
1 6 2 5 3 4
```

✔ All sum to 7 and are unique.

✔ Final Answer Summary:

#### 1. Number Bonds of 5
```
5 5 5
/ \ / \ / \
0 5 1 4 2 3
```

#### 2. Number Bonds of 6
```
6 6 6
/ \ / \ / \
1 5 2 4 3 3
```

#### 3. Number Bonds of 7
```
7 7 7
/ \ / \ / \
1 6 2 5 3 4
```

> Note: There are multiple correct answers. As long as the two numbers below each total add up to the top number and are unique (not repeating the same pair), it's correct.

📝 Explanation:

- Number bonds help children understand addition and subtraction.
- They show how a number can be broken into parts.
- This builds foundational math skills like mental arithmetic and understanding part-whole relationships.
