Draw an array for 12x7 (You don;t have to draw all the boxes inside, just the shape and the dimensions.) How would you break up this array into two smaller arrays? Show your two smaller arrays an your drawing. Then fill in the equation and solve the problem.

To draw an array for 12x7, you first need to draw a rectangle with 12 rows and 7 columns. Each box inside the rectangle represents one unit.

Here is the drawing of a 12x7 array:

To break this array into two smaller arrays, we can divide it vertically by splitting it into two halves. Let's call the smaller arrays A and B.

Here is the drawing of the two smaller arrays:

Array A:
```

|____|____|____|____|____|
|____|____|____|____|____|
|____|____|____|____|____|
|____|____|____|____|____|
|____|____|____|____|____|
|____|____|____|____|____|
|____|____|____|____|____|
```

Array B:
```

```

Now let's fill in the equation and solve the problem.

Equation: 12 x 7 = (A) + (B)

We know that the original array has a total of 12 rows and 7 columns. Array A has 7 columns same as the original array, but it has half of the rows, which is 6. So, we can calculate the number of rows in Array B by subtracting 6 from the total number of rows, which is 12.

Let's solve it:

12 x 7 = (A) + (B)
84 = 42 + (B)
84 - 42 = (B)
42 = (B)

Therefore, Array B has 42 boxes.

To summarize:
- Array A has 6 rows and 7 columns.
- Array B has 6 rows and 2 columns.

I hope this explanation helps you understand how to draw an array, break it into smaller arrays, and solve the problem using the equation.
