🌈 Task:

How many ways can you find to make 10?

You are given 10 blank equations like:
```
__ + __ = 10
```
And you need to fill in the blanks with two numbers that add up to 10.

✔ Solution:

We need to find all unique pairs of whole numbers (from 0 to 10) that sum to 10. Since the order doesn't matter (e.g., 2+8 and 8+2 are the same pair), we’ll list them in ascending order to avoid duplicates.

Here are all the possible combinations:

1. 0 + 10 = 10
2. 1 + 9 = 10
3. 2 + 8 = 10
4. 3 + 7 = 10
5. 4 + 6 = 10
6. 5 + 5 = 10
7. 6 + 4 = 10 ← This is the same as #4, so we skip it if avoiding duplicates
8. 7 + 3 = 10 ← Same as #3
9. 8 + 2 = 10 ← Same as #2
10. 9 + 1 = 10 ← Same as #1
11. 10 + 0 = 10 ← Same as #1

So, the unique pairs are:

- 0 + 10
- 1 + 9
- 2 + 8
- 3 + 7
- 4 + 6
- 5 + 5

✔ That’s 6 unique ways to make 10 using whole numbers.

But wait — the worksheet has 10 blanks, so it likely wants all combinations including reversals, or allows repeats.

Let’s assume the goal is to fill in 10 equations with any valid pairs (including reversed ones). Then we can use:

1. 0 + 10 = 10
2. 1 + 9 = 10
3. 2 + 8 = 10
4. 3 + 7 = 10
5. 4 + 6 = 10
6. 5 + 5 = 10
7. 6 + 4 = 10
8. 7 + 3 = 10
9. 8 + 2 = 10
10. 9 + 1 = 10

That gives us 10 equations — perfect for filling the worksheet!

> Note: The last one, 10 + 0 = 10, is also valid, but since we already used 0 + 10, it's just the reverse.

✔ Final Answer (for the worksheet):

Fill in the blanks like this:

```
0 + 10 = 10 1 + 9 = 10
2 + 8 = 10 3 + 7 = 10
4 + 6 = 10 5 + 5 = 10
6 + 4 = 10 7 + 3 = 10
8 + 2 = 10 9 + 1 = 10
```

This uses 10 different number pairs (including reversals), which fills the sheet perfectly.

💡 Educational Purpose:

This activity teaches:
- Addition facts that sum to 10
- Number bonds
- Commutative property of addition (e.g., 3+7 = 7+3)
- Pattern recognition

It's a great way to build foundational math skills in early learners.
