You're working on a worksheet that teaches
multi-digit multiplication using the partial products method — breaking down the multiplier into its tens and ones place, multiplying each part separately, and then adding the results.
Let’s solve problems 2 through 9 step by step, following the same format as problem #1.

Problem 2: 62 × 23
Break 23 into 20 + 3.
- First, multiply 62 × 3 =
186
- Then, multiply 62 × 20 =
1240 (shift one place left — add a zero)
- Add them: 186 + 1240 =
1426
✔ Answer: 1426
```

Problem 3: 42 × 22
Break 22 into 20 + 2.
- 42 × 2 =
84
- 42 × 20 =
840
- Add: 84 + 840 =

Problem 6: 68 × 41
Break 41 into 40 + 1.
- 68 × 1 =
68
- 68 × 40 =
2720
- Add: 68 + 2720 =
2788
✔ Answer: 2788
```
6 8
x 4 1
-----
6 8 ← 68 × 1
2 7 2 0 ← 68 × 40
-------
2 7 8 8
```

Problem 7: 121 × 22
Break 22 into 20 + 2.
- 121 × 2 =
242
- 121 × 20 =
2420
- Add: 242 + 2420 =
2662
✔ Answer: 2662
```
1 2 1
x 2 2
-------
2 4 2 ← 121 × 2
2 4 2 0 ← 121 × 20
-------
2 6 6 2
```

Problem 8: 223 × 23
Break 23 into 20 + 3.
- 223 × 3 =
669
- 223 × 20 =
4460
- Add: 669 + 4460 =
5129
✔ Answer: 5129
```
2 2 3
x 2 3

Problem 9: 411 × 32
Break 32 into 30 + 2.
- 411 × 2 =
822
- 411 × 30 =
12330
- Add: 822 + 12330 =
13152
✔ Answer: 13152

## 💡 Teaching Tip:
This method reinforces
place value understanding and helps students see *why* we shift numbers when multiplying by tens or hundreds. It’s a great foundation before moving to the standard algorithm!
Let me know if you’d like a printable version or more practice!
