Let's solve each addition sentence by converting it into a multiplication sentence. The key idea is:
>
Multiplication is repeated addition.
> So, if a number is added *n* times, we can write it as:
>
(number) × (how many times it's added)
---
Let's go through each one:
---
a. Already done:
`3 + 3 + 3 + 3 = 3 × 4 = 12`
✔ 3 is added 4 times → 3 × 4 = 12
---
b. `4 + 4 + 4 + 4 + 4`
→ 4 is added
5 times
So:
4 × 5 = 20
---
c. `7 + 7 + 7 + 7 + 7 + 7`
→ 7 is added
6 times
So:
7 × 6 = 42
---
d. `1 + 1 + 1 + 1`
→ 1 is added
4 times
So:
1 × 4 = 4
---
e. `2 + 2`
→ 2 is added
2 times
So:
2 × 2 = 4
---
f. `3 + 3 + 3`
→ 3 is added
3 times
So:
3 × 3 = 9
---
g. `6 + 6 + 6 + 6 + 6 + 6 + 6`
→ 6 is added
7 times
So:
6 × 7 = 42
---
h. `5 + 5 + 5 + 5`
→ 5 is added
4 times
So:
5 × 4 = 20
---
i. `8 + 8 + 8 + 8 + 8`
→ 8 is added
5 times
So:
8 × 5 = 40
---
j. `1 + 1 + 1 + 1 + 1 + 1 + 1`
→ 1 is added
7 times
So:
1 × 7 = 7
---
✔ Final Answers:
| Problem | Multiplication Sentence |
|--------|--------------------------|
| b. | 4 × 5 = 20 |
| c. | 7 × 6 = 42 |
| d. | 1 × 4 = 4 |
| e. | 2 × 2 = 4 |
| f. | 3 × 3 = 9 |
| g. | 6 × 7 = 42 |
| h. | 5 × 4 = 20 |
| i. | 8 × 5 = 40 |
| j. | 1 × 7 = 7 |

🌟 Explanation:
In each case, we counted how many times the same number was added and then wrote it in the form:
>
Number × Number of times added = Product
This shows that
multiplication is a shortcut for repeated addition, which is exactly what this worksheet teaches!
Let me know if you'd like a printable version or visual representation! 😊
Parent Tip: Review the logic above to help your child master the concept of repeated addition worksheet for year.
