Math worksheet for practicing addition to make 10.

The worksheet titled "Make a 10" is designed to help students practice addition problems that sum to 10, using the concept of "making ten" — a foundational skill in early math education. The goal is to identify which pairs of numbers add up to 10.

Let’s go through each problem and solve it step by step:

---

First Row:

1. 8 + 4 = ?
→ 8 + 4 = 12 → Not 10

2. 3 + 5 = ?
→ 3 + 5 = 8 → Not 10

3. 9 + 2 = ?
→ 9 + 2 = 11 → Not 10

4. 4 + 3 = ?
→ 4 + 3 = 7 → Not 10

> Wait — the first one has a circle around 2 and 8, and 10 written beside it. This suggests the instruction is to find two numbers that make 10, not necessarily to compute the given sums.

Let’s re-evaluate based on the title "Make a 10" and the example:

- The first problem shows:
```
2
8
+ 4
----
```
And there's a circle around 2 and 8, with 10 next to it.

So, the idea is: Look at the top two numbers (2 and 8), and see if they make 10.
Yes! 2 + 8 = 10.

But then why is there a "+4"? That seems confusing.

Wait — perhaps the format is this:

Each column has two numbers stacked, and then a third number added below.

So let’s interpret each column as:

```
A
B
+ C
----
```

And the task might be: Which of these additions equal 10?

Let’s check all:

---

Column 1:

```
2
8
+ 4
----
```
→ 2 + 8 + 4 = 14 → Too much
But wait — maybe only top two numbers are considered?

But the example shows 2 and 8 circled, and 10 written beside it. So likely, the top two numbers should add to 10.

Let’s test that:

- Column 1: 2 + 8 = 10 ✔
- Column 2: 3 + 5 = 8 ✘
- Column 3: 9 + 1 = 10 ✔
- Column 4: 4 + 6 = 10 ✔

Now look at the second row:

- Column 1: 7 + 3 = 10 ✔
- Column 2: 5 + 5 = 10 ✔
- Column 3: 8 + 2 = 10 ✔
- Column 4: 1 + 9 = 10 ✔

Third row:

- Column 1: 4 + 6 = 10 ✔
- Column 2: 3 + 7 = 10 ✔
- Column 3: 2 + 8 = 10 ✔
- Column 4: 6 + 5 = 11 ✘

So now we can see the pattern:

> The task is to find which pairs of numbers (the top two in each column) add up to 10.

Then, the third number (+C) might be a distractor or part of a different exercise, but based on the circled 2 and 8, and the label "make a 10", the focus is on pairing the top two numbers to make 10.

✔ Correct Pairs That Make 10:

Let’s list them:

| Column | Top Two Numbers | Sum | Make 10? |
|--------|------------------|-----|----------|
| 1 | 2 + 8 | 10 | ✔ |
| 2 | 3 + 5 | 8 | ✘ |
| 3 | 9 + 1 | 10 | ✔ |
| 4 | 4 + 6 | 10 | ✔ |
| 5 | 7 + 3 | 10 | ✔ |
| 6 | 5 + 5 | 10 | ✔ |
| 7 | 8 + 2 | 10 | ✔ |
| 8 | 1 + 9 | 10 | ✔ |
| 9 | 4 + 6 | 10 | ✔ |
|10 | 3 + 7 | 10 | ✔ |
|11 | 2 + 8 | 10 | ✔ |
|12 | 6 + 5 | 11 | ✘ |

Wait — there are 12 columns, but only 12 problems listed in 3 rows of 4.

Let’s count:

- Row 1: 4 columns
- Row 2: 4 columns
- Row 3: 4 columns

Total: 12 problems

We already checked:

Row 1:

1. 2 + 8 = 10 ✔
2. 3 + 5 = 8 ✘
3. 9 + 1 = 10 ✔
4. 4 + 6 = 10 ✔

Row 2:

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

Row 3:

9. 4 + 6 = 10 ✔
10. 3 + 7 = 10 ✔
11. 2 + 8 = 10 ✔
12. 6 + 5 = 11 ✘

So only one pair does NOT make 10: 6 + 5 = 11

---

✔ Final Answer:

The student should circle the top two numbers in each column that add to 10.

Correct pairs (that make 10):

1. 2 + 8
2. 9 + 1
3. 4 + 6
4. 7 + 3
5. 5 + 5
6. 8 + 2
7. 1 + 9
8. 4 + 6
9. 3 + 7
10. 2 + 8
11. 6 + 5 → ✘ (does not make 10)

So only column 12 (last one) does not make 10.

📌 Explanation for Students:

The goal is to find two numbers that add up to 10. For example:
- 2 and 8 → 2 + 8 = 10
- 9 and 1 → 9 + 1 = 10
- 5 and 5 → 5 + 5 = 10

You do not need to add the bottom number unless instructed.

In this worksheet, you’re supposed to look at the top two numbers in each column and circle them if they make 10.

Only one column (the last one) has numbers that don’t make 10: 6 + 5 = 11.

---

✔ Summary:

- Number of pairs that make 10: 11 out of 12
- One pair that does NOT make 10: 6 + 5 = 11

So the student should circle the top two numbers in each column except the last one.

---

Final Answer:

Circle the top two numbers in each column if they add up to 10. The only pair that does not make 10 is 6 and 5 (in the last column).

✔ All other pairs (2+8, 9+1, 4+6, 7+3, 5+5, 8+2, 1+9, 4+6, 3+7, 2+8) make 10.

This helps build number sense and mental math skills.
