Multiplication practice worksheet using the box method for two-digit numbers.

I need to solve the multiplication problems shown in the image. The worksheet shows six multiplication problems using a grid method, where I need to multiply two-digit numbers and fill in the intermediate steps and final answers.

Let me start by solving each problem one by one:

1) 60 × 12
2) 66 × 67
3) 60 × 88
4) 89 × 14
5) 34 × 53
6) 58 × 42

I'll calculate each of these step by step.

For problem 1: 60 × 12
- 60 × 10 = 600
- 60 × 2 = 120
- 600 + 120 = 720

For problem 2: 66 × 67
- 66 × 60 = 3960
- 66 × 7 = 462
- 3960 + 462 = 4422

For problem 3: 60 × 88
- 60 × 80 = 4800
- 60 × 8 = 480
- 4800 + 480 = 5280

For problem 4: 89 × 14
- 89 × 10 = 890
- 89 × 4 = 356
- 890 + 356 = 1246

For problem 5: 34 × 53
- 34 × 50 = 1700
- 34 × 3 = 102
- 1700 + 102 = 1802

For problem 6: 58 × 42
- 58 × 40 = 2320
- 58 × 2 = 116
- 2320 + 116 = 2436

Now I'll provide the complete solution for each problem with the intermediate steps as shown in the grid format.

Problem 1: 60 × 12
- First row: 60 × 2 = 120 (fill in 120 in the top row of the grid)
- Second row: 60 × 10 = 600 (fill in 600 in the bottom row of the grid)
- Sum: 120 + 600 = 720 (fill in 720 below the plus sign)

Problem 2: 66 × 67
- First row: 66 × 7 = 462 (fill in 462 in the top row of the grid)
- Second row: 66 × 60 = 3960 (fill in 3960 in the bottom row of the grid)
- Sum: 462 + 3960 = 4422 (fill in 4422 below the plus sign)

Problem 3: 60 × 88
- First row: 60 × 8 = 480 (fill in 480 in the top row of the grid)
- Second row: 60 × 80 = 4800 (fill in 4800 in the bottom row of the grid)
- Sum: 480 + 4800 = 5280 (fill in 5280 below the plus sign)

Problem 4: 89 × 14
- First row: 89 × 4 = 356 (fill in 356 in the top row of the grid)
- Second row: 89 × 10 = 890 (fill in 890 in the bottom row of the grid)
- Sum: 356 + 890 = 1246 (fill in 1246 below the plus sign)

Problem 5: 34 × 53
- First row: 34 × 3 = 102 (fill in 102 in the top row of the grid)
- Second row: 34 × 50 = 1700 (fill in 1700 in the bottom row of the grid)
- Sum: 102 + 1700 = 1802 (fill in 1802 below the plus sign)

Problem 6: 58 × 42
- First row: 58 × 2 = 116 (fill in 116 in the top row of the grid)
- Second row: 58 × 40 = 2320 (fill in 2320 in the bottom row of the grid)
- Sum: 116 + 2320 = 2436 (fill in 2436 below the plus sign)

The solutions are:
1) 720
2) 4422
3) 5280
4) 1246
5) 1802
6) 2436
