Number Bonds Worksheet - Fill in the missing numbers for 8, 9, and 10.

Let's solve this step by step.

What are Number Bonds?

Number bonds are pairs of numbers that add up to a given total. For example, the number bonds of 8 are pairs of numbers that sum to 8, like 3 + 5 = 8.

We need to fill in three unique number bonds for each of the numbers: 8, 9, and 10.

---

🔹 Problem 1: Number Bonds of 8

We need any 3 unique pairs that add up to 8.

Examples:
- 1 + 7 = 8 → (1, 7)
- 2 + 6 = 8 → (2, 6)
- 3 + 5 = 8 → (3, 5)

> Note: We can also use (4 + 4), but since it's not two different numbers, it's still valid unless specified otherwise. But "unique" usually means distinct combinations — so (4,4) is fine if allowed, but let’s avoid duplicates.

So, three unique number bonds of 8:
1. 1 and 7
2. 2 and 6
3. 3 and 5

✔ You can write these in any order.

🔹 Problem 2: Number Bonds of 9

Find 3 unique pairs that add up to 9.

Examples:
- 1 + 8 = 9 → (1, 8)
- 2 + 7 = 9 → (2, 7)
- 3 + 6 = 9 → (3, 6)

Other options: (4,5), (0,9), etc.

Choose any 3 unique ones.

So:
1. 1 and 8
2. 2 and 7
3. 3 and 6

✔ These are all valid and unique.

🔹 Problem 3: Number Bonds of 10

Find 3 unique pairs that add up to 10.

Examples:
- 1 + 9 = 10 → (1, 9)
- 2 + 8 = 10 → (2, 8)
- 3 + 7 = 10 → (3, 7)

Other options: (4,6), (5,5), (0,10)

So pick:
1. 1 and 9
2. 2 and 8
3. 3 and 7

✔ All valid and unique.

---

✔ Final Answer:

#### 1. Number Bonds of 8:
```
8 8 8
/ \ / \ / \
1 7 2 6 3 5
```

#### 2. Number Bonds of 9:
```
9 9 9
/ \ / \ / \
1 8 2 7 3 6
```

#### 3. Number Bonds of 10:
```
10 10 10
/ \ / \ / \
1 9 2 8 3 7
```

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

For example, you could also use:
- For 10: (4,6), (5,5), (0,10) — just make sure they're different from each other.

But the ones above are simple and commonly used.

✔ Summary:

You’ve successfully filled in 3 unique number bonds for 8, 9, and 10 using addition pairs. This helps build foundational math skills in understanding how numbers relate to each other.
