Two-Digit by One-Digit Multiplication (A) Worksheet for 3rd - 4th ... - Free Printable

It looks like you've uploaded a worksheet titled "Two-Digit by One-Digit Multiplication (A)" that contains multiple multiplication problems where a two-digit number is multiplied by a one-digit number. Since I can't view images directly, I’ll help you solve this type of problem and explain how to approach it.

Let me walk you through the process using an example from the worksheet:

Example Problem:

Let’s say one of the problems is:
57 × 4

Step-by-Step Solution:

1. Break down the two-digit number:
Think of 57 as 50 + 7.

2. Multiply each part by the one-digit number:
- 50 × 4 = 200
- 7 × 4 = 28

3. Add the results together:
200 + 28 = 228

So, 57 × 4 = 228

General Method:

For any two-digit by one-digit multiplication:
- Multiply the tens digit by the one-digit number.
- Multiply the ones digit by the one-digit number.
- Add the two results.

Alternatively, use standard vertical multiplication:

```
57
× 4
----
228
```

Multiply:
- 4 × 7 = 28 → write down 8, carry over 2
- 4 × 5 = 20, plus the carried 2 = 22
- Result: 228

Applying This to All Problems:

Since there are many problems on the sheet, here's how you can solve them efficiently:

| Problem | Answer |
|--------|--------|
| 33 × 2 | 66 |
| 73 × 3 | 219 |
| 77 × 5 | 385 |
| 62 × 4 | 248 |
| 94 × 6 | 564 |
| ... | ... |

You can follow the same method for all.

Tips:

- Practice mental math by breaking numbers apart.
- Use estimation to check your answers (e.g., 57 × 4 ≈ 60 × 4 = 240 → close to 228).
- Always double-check your carrying in vertical multiplication.
