Multiplication as Repeated Addition worksheet for elementary students.

Let's solve the worksheet step by step. The goal is to understand multiplication as repeated addition and fill in the missing parts of each row.

---

🔹 Understanding the Concept:

Multiplication is a shortcut for repeated addition. For example:
- $ 3 \times 4 $ means adding 3 four times: $ 3 + 3 + 3 + 3 = 12 $

We’ll use this idea to complete the table.

---

✔ Step-by-step Solutions:

#### Row 1:
- Multiplication: $ 7 \times 5 $
- Repeated Addition: $ 3 + 3 + 3 + 3 = ? $ ← This doesn't match!

Wait — the repeated addition shown is 3 + 3 + 3 + 3, which equals 12, but that’s not related to $ 7 \times 5 $. So there's an error here.

But let's look carefully. The repeated addition column is meant to show the same value as the multiplication. So we need to fix or interpret what's going on.

Actually, looking at the structure:
- The multiplication side has problems like $ 7 \times 5 $
- The repeated addition side has expressions like $ 3+3+3+3 $, which seems unrelated unless it's supposed to be filled in.

Wait — perhaps the repeated addition is given for some rows, and we need to fill in the missing multiplication or complete the expression?

Let’s go row by row.

---

📝 Let’s analyze each row:

#### Row 1:
- Multiplication: $ 7 \times 5 = ? $
- Repeated Addition: $ 3 + 3 + 3 + 3 = ? $

This is not correct. $ 3+3+3+3 = 12 $, but $ 7 \times 5 = 35 $. So clearly, the repeated addition should reflect five 7s (or seven 5s), not 3s.

So likely, the repeated addition is missing and needs to be filled in based on the multiplication.

But wait — in this row, the repeated addition is already written as $ 3 + 3 + 3 + 3 $, which is wrong. That suggests a mistake in the worksheet.

Alternatively, maybe the repeated addition is given for some rows, and we need to find the multiplication?

Let’s check other rows.

---

#### Row 2:
- Multiplication: $ 3 \times 10 = ? $
- Repeated Addition: $ 6 + 6 + 6 + 6 + 6 = ? $

$ 6+6+6+6+6 = 30 $, and $ 3 \times 10 = 30 $. But the repeated addition is five 6s → $ 5 \times 6 = 30 $, not $ 3 \times 10 $.

So again, mismatch.

Hmm.

Wait — maybe the repeated addition is supposed to represent the multiplication? Then we must fix it.

Let’s suppose that the repeated addition is given in some rows, and we are to find the matching multiplication, or vice versa.

But the directions say: *"Solve the math problems and fill in the missing multiplication or repeated addition sentence."*

So in each row, one is missing — either the multiplication or the repeated addition.

Let’s re-express each row with what is given and what is missing.

---

✔ Let’s Re-analyze Each Row:

#### Row 1:
- Multiplication: $ 7 \times 5 = ? $
- Repeated Addition: $ 3 + 3 + 3 + 3 = ? $

→ Wait, $ 3+3+3+3 = 12 $, but $ 7 \times 5 = 35 $. These don’t match.

But the repeated addition shows only four 3s → $ 4 \times 3 = 12 $

So this row is inconsistent.

But maybe the repeated addition is not supposed to be for $ 7 \times 5 $? That can't be.

Wait — perhaps the repeated addition is given incorrectly, or it's a typo.

Let’s look at Row 2:

#### Row 2:
- Multiplication: $ 3 \times 10 = ? $
- Repeated Addition: $ 6 + 6 + 6 + 6 + 6 = ? $

→ $ 6+6+6+6+6 = 30 $, and $ 3 \times 10 = 30 $ → so both equal 30.

But $ 6+6+6+6+6 = 5 \times 6 $, not $ 3 \times 10 $. So why is this listed under $ 3 \times 10 $?

It could be that the repeated addition is correct, and the multiplication is missing? But no — multiplication is given.

Wait — maybe the repeated addition is meant to be completed, and the multiplication is also to be solved.

But the format is:

| Multiplication | Repeated Addition |
|----------------|--------------------|
| $ 7 \times 5 $ | $ 3+3+3+3 = $ |

That doesn't make sense.

Wait — perhaps the repeated addition is already filled in for some rows, and we need to write the multiplication that matches it?

Let’s try that.

---

🔍 New Interpretation:

Maybe the repeated addition is given, and we need to write the equivalent multiplication.

Let’s test that.

#### Row 1:
- Repeated Addition: $ 3 + 3 + 3 + 3 = 12 $
- So multiplication: $ 4 \times 3 = 12 $ → but the multiplication says $ 7 \times 5 $, which is 35.

Mismatch.

But the multiplication is given as $ 7 \times 5 $, so perhaps the repeated addition is missing and should be $ 7 + 7 + 7 + 7 + 7 $ or $ 5 + 5 + 5 + 5 + 5 + 5 + 5 $

So maybe the repeated addition is missing, and we have to fill it in.

But in Row 1, the repeated addition is already written: $ 3+3+3+3 $

That’s confusing.

Wait — let’s look at Row 3:

#### Row 3:
- Multiplication: $ 5 \times 8 = ? $
- Repeated Addition: $ 5 + 5 + 5 = ? $

$ 5+5+5 = 15 $, but $ 5 \times 8 = 40 $. So again, mismatch.

But $ 5+5+5 $ is only three 5s → $ 3 \times 5 = 15 $, not $ 5 \times 8 $

So something is off.

Now Row 4:
- Multiplication: $ 6 \times 2 = ? $
- Repeated Addition: $ 10 + 10 = ? $

$ 10+10 = 20 $, $ 6 \times 2 = 12 $. Not matching.

Row 5:
- Multiplication: $ 2 \times 5 = ? $
- Repeated Addition: $ 4 + 4 + 4 + 4 = ? $

$ 4+4+4+4 = 16 $, $ 2 \times 5 = 10 $. No.

So all the repeated additions are wrong for the given multiplications.

But wait — perhaps the repeated addition is given, and the multiplication is missing?

Let’s try that.

For example:

#### Row 1:
- Repeated Addition: $ 3+3+3+3 = 12 $
- So multiplication: $ 4 \times 3 = 12 $

But the multiplication says $ 7 \times 5 $, which is 35.

No.

Wait — maybe the repeated addition is not for the multiplication in the same row? That doesn’t make sense.

Perhaps there’s a typo in the worksheet.

Let me re-express the intended pattern.

Looking at the last row:

- Multiplication: $ 2 \times 5 = ? $
- Repeated Addition: $ 4 + 4 + 4 + 4 = ? $

Again, $ 4+4+4+4 = 16 $, $ 2 \times 5 = 10 $

Not matching.

But notice: $ 4+4+4+4 = 4 \times 4 = 16 $

So if the repeated addition is $ 4+4+4+4 $, then multiplication should be $ 4 \times 4 $

But it's listed as $ 2 \times 5 $

This suggests that the repeated addition might be independent, and we need to match them correctly.

Wait — maybe the repeated addition is given, and we need to write the multiplication that corresponds to it?

Let’s assume that:

- In each row, one side is given, and we need to fill in the other.

But in Row 1, multiplication is given: $ 7 \times 5 $, and repeated addition is given as $ 3+3+3+3 $

But they don’t match.

Unless... the repeated addition is not for that multiplication, but instead, the repeated addition is to be completed based on the multiplication.

But it’s already filled in.

Wait — maybe the repeated addition is partially filled, and we need to complete it?

But it's fully written.

Let’s look at Row 2:
- $ 3 \times 10 = ? $
- $ 6 + 6 + 6 + 6 + 6 = ? $

If $ 6+6+6+6+6 = 30 $, and $ 3 \times 10 = 30 $, so both give 30.

So perhaps the repeated addition is correct, and the multiplication is also correct, even though $ 6+6+6+6+6 $ is $ 5 \times 6 $, not $ 3 \times 10 $.

But they are equal in value: both equal 30.

So maybe the idea is: both expressions equal the same number, and we need to solve both.

Ah! Now I see.

The intention is:
- You are given a multiplication problem and a repeated addition problem.
- Both may be incomplete.
- You need to solve the multiplication and the repeated addition, and possibly fill in the missing parts.

But in many cases, the repeated addition is already given, but it's not matching.

Wait — let’s look at Row 3:
- $ 5 \times 8 = ? $
- $ 5 + 5 + 5 = ? $

$ 5+5+5 = 15 $, $ 5 \times 8 = 40 $

No.

But perhaps the repeated addition is meant to be $ 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 $ (eight 5s)

But it's written as $ 5 + 5 + 5 $, which is only three.

So likely, the repeated addition is incorrectly printed.

Wait — maybe the repeated addition is given, and the multiplication is to be filled in?

Let’s try that.

Suppose the repeated addition is correct, and we need to write the multiplication.

#### Row 1:
- $ 3+3+3+3 = 12 $ → $ 4 \times 3 = 12 $
- But multiplication says $ 7 \times 5 $, which is 35

No.

#### Row 2:
- $ 6+6+6+6+6 = 30 $ → $ 5 \times 6 = 30 $
- But multiplication says $ 3 \times 10 = 30 $, which is also 30

So both are valid representations of 30.

So maybe the multiplication is $ 3 \times 10 $, and the repeated addition is $ 6+6+6+6+6 $, both equal 30.

But $ 3 \times 10 $ is not the same as $ 6+6+6+6+6 $, but they are equal in value.

So perhaps the task is to solve both sides and verify.

But the directions say: "fill in the missing multiplication or repeated addition sentence."

So likely, one is missing.

But in the image, both are present.

Wait — let’s look closely at the image.

In the first row:
- Multiplication: $ 7 \times 5 = $ (empty)
- Repeated Addition: $ 3 + 3 + 3 + 3 = $ (empty)

Wait — actually, the repeated addition is written as $ 3 + 3 + 3 + 3 = $, but no answer, so we need to compute it.

Similarly, $ 7 \times 5 = $ is empty.

So the task is to solve both.

But they are not related.

Unless the repeated addition is not for $ 7 \times 5 $, but for another problem.

But it's in the same row.

This is confusing.

Wait — perhaps the repeated addition is supposed to be the same as the multiplication.

So for $ 7 \times 5 $, the repeated addition should be $ 7 + 7 + 7 + 7 + 7 $ or $ 5 + 5 + 5 + 5 + 5 + 5 + 5 $

But it's written as $ 3+3+3+3 $, which is wrong.

So likely, the repeated addition is a typo.

But let’s assume that the repeated addition is given, and we need to find the multiplication that matches it.

Let’s try that.

✔ Let’s Assume: The repeated addition is given, and we need to write the multiplication that represents it.

Then:

#### Row 1:
- Repeated Addition: $ 3 + 3 + 3 + 3 = 12 $
- So multiplication: $ 4 \times 3 = 12 $
- But the multiplication is given as $ 7 \times 5 $, which is 35

No.

But perhaps the multiplication is missing, and we need to fill it in.

But it’s written as $ 7 \times 5 $

Unless it’s a placeholder, and we need to replace it.

But that doesn’t make sense.

Another possibility: the repeated addition is to be completed, and the multiplication is given.

So for $ 7 \times 5 $, we need to write $ 7 + 7 + 7 + 7 + 7 $ or $ 5 + 5 + 5 + 5 + 5 + 5 + 5 $

But the repeated addition is written as $ 3+3+3+3 $, which is not related.

So likely, the repeated addition is incorrect.

Given the confusion, let’s look at the last row:

- Multiplication: $ 2 \times 5 = ? $
- Repeated Addition: $ 4 + 4 + 4 + 4 = ? $

$ 2 \times 5 = 10 $, $ 4+4+4+4 = 16 $

No.

But if the repeated addition were $ 2 + 2 + 2 + 2 + 2 $, that would be $ 5 \times 2 = 10 $

Or $ 5 + 5 = 10 $

So perhaps the repeated addition is supposed to be $ 2 + 2 + 2 + 2 + 2 $ or $ 5 + 5 $

But it's written as $ 4+4+4+4 $

So it seems like the repeated addition is not matching any of the multiplications.

Unless the repeated addition is not for the multiplication in the same row.

But that would be illogical.

✔ Final Interpretation:

After careful analysis, I believe there is a typo in the worksheet.

The intended structure is:

- Each row has a multiplication problem.
- The repeated addition should be the same as the multiplication (e.g., $ 7 \times 5 $ should be $ 7+7+7+7+7 $ or $ 5+5+5+5+5+5+5 $)
- But in the image, the repeated addition is wrong.

However, in some rows, the repeated addition is correct for a different multiplication.

For example:

- $ 6+6+6+6+6 = 30 $, and $ 3 \times 10 = 30 $ — both are 30, but not equivalent expressions.

So perhaps the task is simply to solve both and write the answers.

Let’s do that.

---

✔ Corrected Solution (Assuming We Solve Both):

#### Row 1:
- $ 7 \times 5 = 35 $
- $ 3 + 3 + 3 + 3 = 12 $

But these are not related. So likely, the repeated addition should be $ 7+7+7+7+7 = 35 $ or $ 5+5+5+5+5+5+5 = 35 $

So probably, the repeated addition is supposed to be $ 7+7+7+7+7 = $, but it's written as $ 3+3+3+3 $

So this is a mistake.

But let’s assume that the repeated addition is given, and we need to compute its sum, and the multiplication is to be computed.

So we'll just compute both.

---

✔ Let's Solve What We Can:

#### Row 1:
- $ 7 \times 5 = 35 $
- $ 3 + 3 + 3 + 3 = 12 $

#### Row 2:
- $ 3 \times 10 = 30 $
- $ 6 + 6 + 6 + 6 + 6 = 30 $

#### Row 3:
- $ 5 \times 8 = 40 $
- $ 5 + 5 + 5 = 15 $

#### Row 4:
- $ 6 \times 2 = 12 $
- $ 10 + 10 = 20 $

#### Row 5:
- $ 2 \times 5 = 10 $
- $ 4 + 4 + 4 + 4 = 16 $

None of the repeated additions match the multiplication.

But notice: in Row 2, both are 30.

In Row 3, $ 5+5+5 = 15 $, but $ 5 \times 8 = 40 $

So likely, the repeated addition should be $ 5+5+5+5+5+5+5+5 = 40 $ (eight 5s)

Similarly, for $ 6 \times 2 = 12 $, repeated addition should be $ 6+6 = 12 $ or $ 2+2+2+2+2+2 = 12 $

For $ 2 \times 5 = 10 $, repeated addition should be $ 2+2+2+2+2 = 10 $ or $ 5+5 = 10 $

For $ 7 \times 5 = 35 $, repeated addition should be $ 7+7+7+7+7 = 35 $ or $ 5+5+5+5+5+5+5 = 35 $

So the repeated addition in the worksheet is incorrect.

But perhaps the repeated addition is given, and we need to write the multiplication that matches it.

Let’s try that.

✔ Alternative Approach: Use Repeated Addition to Find Multiplication

#### Row 1:
- $ 3+3+3+3 = 12 $ → $ 4 \times 3 = 12 $
- So multiplication should be $ 4 \times 3 $, but it's written as $ 7 \times 5 $

No.

#### Row 2:
- $ 6+6+6+6+6 = 30 $ → $ 5 \times 6 = 30 $
- But multiplication is $ 3 \times 10 = 30 $

Both are valid, but not the same.

So perhaps the task is to solve both and write the answers.

✔ Final Answer (Assuming We Just Compute the Values):

Let’s fill in the answers as per the given expressions.

| Multiplication | Repeated Addition |
|----------------|--------------------|
| $ 7 \times 5 = \boxed{35} $ | $ 3 + 3 + 3 + 3 = \boxed{12} $ |
| $ 3 \times 10 = \boxed{30} $ | $ 6 + 6 + 6 + 6 + 6 = \boxed{30} $ |
| $ 5 \times 8 = \boxed{40} $ | $ 5 + 5 + 5 = \boxed{15} $ |
| $ 6 \times 2 = \boxed{12} $ | $ 10 + 10 = \boxed{20} $ |
| $ 2 \times 5 = \boxed{10} $ | $ 4 + 4 + 4 + 4 = \boxed{16} $ |

But this is not showing multiplication as repeated addition.

✔ Correct Way: Fix the Repeated Addition to Match Multiplication

The intended solution is:

| Multiplication | Repeated Addition |
|----------------|--------------------|
| $ 7 \times 5 = 35 $ | $ 7 + 7 + 7 + 7 + 7 = 35 $ or $ 5 + 5 + 5 + 5 + 5 + 5 + 5 = 35 $ |
| $ 3 \times 10 = 30 $ | $ 3 + 3 + 3 + \dots $ (10 times) or $ 10 + 10 + 10 = 30 $ |
| $ 5 \times 8 = 40 $ | $ 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 40 $ |
| $ 6 \times 2 = 12 $ | $ 6 + 6 = 12 $ |
| $ 2 \times 5 = 10 $ | $ 2 + 2 + 2 + 2 + 2 = 10 $ |

But the worksheet has incorrect repeated addition.

✔ Conclusion:

There is a mistake in the worksheet. The repeated addition does not match the multiplication.

However, if we assume that the repeated addition is given, and we need to compute its sum, and the multiplication is to be solved, then:

#### Final Answers:

| Multiplication | Repeated Addition |
|----------------|--------------------|
| $ 7 \times 5 = \boxed{35} $ | $ 3 + 3 + 3 + 3 = \boxed{12} $ |
| $ 3 \times 10 = \boxed{30} $ | $ 6 + 6 + 6 + 6 + 6 = \boxed{30} $ |
| $ 5 \times 8 = \boxed{40} $ | $ 5 + 5 + 5 = \boxed{15} $ |
| $ 6 \times 2 = \boxed{12} $ | $ 10 + 10 = \boxed{20} $ |
| $ 2 \times 5 = \boxed{10} $ | $ 4 + 4 + 4 + 4 = \boxed{16} $ |

But this is not teaching multiplication as repeated addition.

✔ Recommended Correction:

The repeated addition should be:

- $ 7 \times 5 $ → $ 7+7+7+7+7 = 35 $
- $ 3 \times 10 $ → $ 3+3+3+3+3+3+3+3+3+3 = 30 $ or $ 10+10+10 = 30 $
- $ 5 \times 8 $ → $ 5+5+5+5+5+5+5+5 = 40 $
- $ 6 \times 2 $ → $ 6+6 = 12 $
- $ 2 \times 5 $ → $ 2+2+2+2+2 = 10 $

So the worksheet has errors.

✔ If you are to fill in the blanks as given:

Then simply compute the values.

Final Answer:

| Multiplication | Repeated Addition |
|----------------|--------------------|
| $ 7 \times 5 = \boxed{35} $ | $ 3 + 3 + 3 + 3 = \boxed{12} $ |
| $ 3 \times 10 = \boxed{30} $ | $ 6 + 6 + 6 + 6 + 6 = \boxed{30} $ |
| $ 5 \times 8 = \boxed{40} $ | $ 5 + 5 + 5 = \boxed{15} $ |
| $ 6 \times 2 = \boxed{12} $ | $ 10 + 10 = \boxed{20} $ |
| $ 2 \times 5 = \boxed{10} $ | $ 4 + 4 + 4 + 4 = \boxed{16} $ |

But note: the repeated addition does not represent the multiplication.

🟩 Recommendation: The worksheet has errors. It should have consistent expressions.

For example, for $ 7 \times 5 $, the repeated addition should be $ 7+7+7+7+7 $, not $ 3+3+3+3 $.

Otherwise, the concept is not being taught correctly.
