Repeated Addition - Free Printable

Let's solve each problem in the "Repeated Addition" worksheet step by step. The goal is to convert repeated addition into multiplication and vice versa, using visual arrays or groups.

Top Left:

Visual: 3 groups of 3 squares
Problem:
`3 + 3 + 3 = ___`
`4 × 3 = ___`

- `3 + 3 + 3 = 9`
- But wait — there are only three groups, so it should be `3 × 3`, not `4 × 3`.
So likely a typo or mislabeling.

But the blank says: `4 × 3 = ___` → that would be `12`, but visually we have only 3 groups of 3.

Wait — let's recheck:
The image shows three gray blocks, each with 3 squares → total: 3 × 3 = 9

So:
- `3 + 3 + 3 = 9`
- `3 × 3 = 9`

But the second line says `4 × 3 = ___` — this doesn’t match the image. Probably an error.

Assuming it's meant to be:
> `3 + 3 + 3 = ___` → 9
> `3 × 3 = ___` → 9

But since it says `4 × 3`, maybe the image is wrong? Let's move on.

Top Right:

Visual: 8 groups of 8 rectangles (long bars)
Problem:
`8 + 8 + 8 = ___`
`3 × 8 = ___`

- `8 + 8 + 8 = 24`
- `3 × 8 = 24`

✔ Correct.

---

Middle Left:

Visual: 2 rows of 10 pink rectangles (each row has 10)
Problem:
`10 + 10 = ___`
`2 × 10 = ___`

- `10 + 10 = 20`
- `2 × 10 = 20`

✔ Correct.

---

Middle Right:

Visual: 7 groups of 2 green rectangles
Problem:
`2 + 2 + 2 + 2 + 2 + 2 + 2 = ___`
`7 × 2 = ___`

- `2 + 2 + 2 + 2 + 2 + 2 + 2 = 14`
- `7 × 2 = 14`

✔ Correct.

---

Bottom Left (first):

Visual: 5 groups of 4 orange rectangles (each group has 4)
Problem:
`___ + ___ + ___ + ___ + ___ = ___`
`___ × ___ = ___`

- Each group has 4, and there are 5 groups →
`4 + 4 + 4 + 4 + 4 = 20`
`5 × 4 = 20`

So fill in:
- `4 + 4 + 4 + 4 + 4 = 20`
- `5 × 4 = 20`

✔ Correct.

Bottom Left (second):

Visual: 4 groups of 6 yellow rectangles (each group has 6)
Problem:
`___ + ___ + ___ + ___ = ___`
`___ × ___ = ___`

- `6 + 6 + 6 + 6 = 24`
- `4 × 6 = 24`

✔ Correct.

---

Bottom Right (first):

Visual: 6 groups of 5 purple rectangles
Problem:
`___ + ___ + ___ + ___ + ___ + ___ = ___`
`___ × ___ = ___`

- `5 + 5 + 5 + 5 + 5 + 5 = 30`
- `6 × 5 = 30`

✔ Correct.

---

Bottom Right (second):

Visual: 3 groups of 9 dark gray rectangles (each group has 9)
Problem:
`___ + ___ + ___ = ___`
`___ × ___ = ___`

- `9 + 9 + 9 = 27`
- `3 × 9 = 27`

✔ Correct.

Final Answers (filled in):

| Problem | Answer |
|--------|--------|
| 3 + 3 + 3 = ___ | 9 |
| 4 × 3 = ___ | 12 *(but image shows only 3 groups, so likely typo)* → Should be 3 × 3 = 9 |
| 8 + 8 + 8 = ___ | 24 |
| 3 × 8 = ___ | 24 |
| 10 + 10 = ___ | 20 |
| 2 × 10 = ___ | 20 |
| 2 + 2 + 2 + 2 + 2 + 2 + 2 = ___ | 14 |
| 7 × 2 = ___ | 14 |
| 4 + 4 + 4 + 4 + 4 = ___ | 20 |
| 5 × 4 = ___ | 20 |
| 6 + 6 + 6 + 6 = ___ | 24 |
| 4 × 6 = ___ | 24 |
| 5 + 5 + 5 + 5 + 5 + 5 = ___ | 30 |
| 6 × 5 = ___ | 30 |
| 9 + 9 + 9 = ___ | 27 |
| 3 × 9 = ___ | 27 |

✔ Correction Note:

The first box has a mismatch:
- Image shows 3 groups of 3 → total = 9
- But it asks for `4 × 3 = ___` → which is 12, but that’s not what's shown.

Likely correction:
It should be:
> `3 + 3 + 3 = 9`
> `3 × 3 = 9`

If the image truly shows 4 groups, then it should be 4 × 3 = 12. But currently, it shows only 3 groups.

So assume it's a typo — correct version is:
> `3 + 3 + 3 = 9`
> `3 × 3 = 9`

| Middle Left | 10 + 10 = 20 | 2 × 10 = 20 |
| Middle Right | 2+2+2+2+2+2+2 = 14 | 7 × 2 = 14 |
| Bottom Left (orange) | 4+4+4+4+4 = 20 | 5 × 4 = 20 |
| Bottom Left (yellow) | 6+6+6+6 = 24 | 4 × 6 = 24 |

✔ All problems solved!
This worksheet teaches the concept that repeated addition is the same as multiplication. For example, adding 4 five times is the same as 5 × 4.
