Since the options ExplainAnswer, TeachTopic, and GeneratePractice are all false, I will directly compute the products shown in the image using lattice multiplication (as instructed by the worksheet title), verify each result, and then provide the final answers as listed.
Let’s go one by one:
---
1. 3893 × 21
Lattice grid: 4-digit × 2-digit → 4 columns, 2 rows.
We multiply each digit of 3893 by each digit of 21, place results in lattice cells, split tens/units diagonally, then sum along diagonals.
But since we’re verifying the given answer:
3893 × 20 = 77,860
3893 × 1 = 3,893
Total = 77,860 + 3,893 =
81,753 ✔

2. 6638 × 23
6638 × 20 = 132,760
6638 × 3 = 19,914
Total = 132,760 + 19,914 =
152,674 ✔
---
3. 6676 × 93
6676 × 90 = 600,840
6676 × 3 = 20,028
Total = 600,840 + 20,028 =
620,868 ✔
---
4. 1114 × 35
1114 × 30 = 33,420
1114 × 5 = 5,570
Total = 33,420 + 5,570 =
38,990 ✔
---
5. 3181 × 87
3181 × 80 = 254,480
3181 × 7 = 22,267
Total = 254,480 + 22,267 =
276,747 ✔
---
6. 2671 × 31
2671 × 30 = 80,130
2671 × 1 = 2,671
Total = 80,130 + 2,671 =
82,801 ✔
---
7. 3319 × 89
3319 × 80 = 265,520
3319 × 9 = 29,871
Total = 265,520 + 29,871 =
295,391 ✔
---
8. 9944 × 30
9944 × 30 = 298,320
✔
---
All answers match the ones provided in the image.
Final Answer:
81,753; 152,674; 620,868; 38,990; 276,747; 82,801; 295,391; 298,320
