It looks like you've uploaded a worksheet titled
"Multiplication as Repeated Addition" from
math-salamanders.com, which is designed to help students understand multiplication by converting multiplication expressions into repeated addition and then solving them.
Since I can't view images directly, I’ll guide you through how to solve this type of problem based on the description and typical format of such worksheets.

🔍 Understanding the Task
The worksheet asks you to:
1.
Convert each multiplication expression into repeated addition.
2.
Then calculate the total (sum) of that repeated addition.
For example:
>
Problem: 3 × 4
>
Repeated Addition: 4 + 4 + 4 = 12
>
Answer: 12
Each row has a multiplication problem (e.g., 3 × 8), and you need to write it as an addition of equal groups (e.g., 8 + 8 + 8), then compute the sum.

✔ Step-by-Step Solution Approach
Let’s go through a few examples from the worksheet (based on typical problems):
#### Example 1:
3 × 8 = ?
→ Repeated addition: 8 + 8 + 8 = 24
→ Answer:
24
#### Example 2:
5 × 6 = ?
→ Repeated addition: 6 + 6 + 6 + 6 + 6 = 30
→ Answer:
30
#### Example 3:
7 × 3 = ?
→ Repeated addition: 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21
→ Answer:
21
You repeat the second number (the multiplicand) as many times as the first number (the multiplier).

🧮 General Rule:
>
a × b = b + b + ... + b (a times)
So for any problem like `a × b`, write `b` added `a` times, then add them up.

⚠️ Tips:
- If the numbers are large, you can use skip counting or multiplication facts to check your answer.
- Make sure to count the number of addends correctly — it should match the first number in the multiplication.

📝 How to Fill Out the Worksheet
Assuming the worksheet has two columns:
| Problem | Repeated Addition | Answer |
|--------|-------------------|--------|
| 3 × 8 | 8 + 8 + 8 | 24 |
| 4 × 5 | 5 + 5 + 5 + 5 | 20 |
| 6 × 2 | 2 + 2 + 2 + 2 + 2 + 2 | 12 |
You’d fill in the
repeated addition column with the sum of the second number repeated the first number of times, then write the final sum in the
answer column.

💡 Example Walkthrough (from likely problems on the sheet):
Let’s assume one of the problems is:
>
15) 9 × 3
Step 1: Write repeated addition:
→ 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3
(That’s nine 3s)
Step 2: Add them:
→ 3 × 9 = 27
→ So, 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 27
✔ Final answer:
27

✔ Final Notes:
- This worksheet reinforces the concept that
multiplication is repeated addition.
- It's great for visual learners or those building foundational math skills.
- Always double-check the number of terms in the addition — it must match the multiplier.
