Practice sheet for lattice multiplication, showing six problems where students multiply 3-digit numbers by 2-digit numbers using the grid method.

To solve the problems, we need to perform the multiplication for each pair of numbers given. Let's go through each problem step by step.

Problem 1: \( 996 \times 79 \)

1. Break down the multiplication:
\[
996 \times 79 = 996 \times (70 + 9) = (996 \times 70) + (996 \times 9)
\]

2. Calculate \( 996 \times 70 \):
\[
996 \times 70 = 996 \times 7 \times 10 = 6972 \times 10 = 69720
\]

3. Calculate \( 996 \times 9 \):
\[
996 \times 9 = 8964
\]

4. Add the results:
\[
69720 + 8964 = 78684
\]

So, the answer is:
\[
\boxed{78684}
\]

Problem 2: \( 580 \times 26 \)

1. Break down the multiplication:
\[
580 \times 26 = 580 \times (20 + 6) = (580 \times 20) + (580 \times 6)
\]

2. Calculate \( 580 \times 20 \):
\[
580 \times 20 = 580 \times 2 \times 10 = 1160 \times 10 = 11600
\]

3. Calculate \( 580 \times 6 \):
\[
580 \times 6 = 3480
\]

4. Add the results:
\[
11600 + 3480 = 15080
\]

So, the answer is:
\[
\boxed{15080}
\]

Problem 3: \( 289 \times 47 \)

1. Break down the multiplication:
\[
289 \times 47 = 289 \times (40 + 7) = (289 \times 40) + (289 \times 7)
\]

2. Calculate \( 289 \times 40 \):
\[
289 \times 40 = 289 \times 4 \times 10 = 1156 \times 10 = 11560
\]

3. Calculate \( 289 \times 7 \):
\[
289 \times 7 = 2023
\]

4. Add the results:
\[
11560 + 2023 = 13583
\]

So, the answer is:
\[
\boxed{13583}
\]

Problem 4: \( 207 \times 44 \)

1. Break down the multiplication:
\[
207 \times 44 = 207 \times (40 + 4) = (207 \times 40) + (207 \times 4)
\]

2. Calculate \( 207 \times 40 \):
\[
207 \times 40 = 207 \times 4 \times 10 = 828 \times 10 = 8280
\]

3. Calculate \( 207 \times 4 \):
\[
207 \times 4 = 828
\]

4. Add the results:
\[
8280 + 828 = 9108
\]

So, the answer is:
\[
\boxed{9108}
\]

Problem 5: \( 204 \times 16 \)

1. Break down the multiplication:
\[
204 \times 16 = 204 \times (10 + 6) = (204 \times 10) + (204 \times 6)
\]

2. Calculate \( 204 \times 10 \):
\[
204 \times 10 = 2040
\]

3. Calculate \( 204 \times 6 \):
\[
204 \times 6 = 1224
\]

4. Add the results:
\[
2040 + 1224 = 3264
\]

So, the answer is:
\[
\boxed{3264}
\]

Problem 6: \( 695 \times 29 \)

1. Break down the multiplication:
\[
695 \times 29 = 695 \times (20 + 9) = (695 \times 20) + (695 \times 9)
\]

2. Calculate \( 695 \times 20 \):
\[
695 \times 20 = 695 \times 2 \times 10 = 1390 \times 10 = 13900
\]

3. Calculate \( 695 \times 9 \):
\[
695 \times 9 = 6255
\]

4. Add the results:
\[
13900 + 6255 = 20155
\]

So, the answer is:
\[
\boxed{20155}
\]

Final Answers:

\[
\boxed{78684, 15080, 13583, 9108, 3264, 20155}
\]
