Explain how to model the multiplication of –6 and 3 on a number line.

I don't know what your teacher expects, but I'd start at -6 and count 6 to the left three times.

Thanks

You're welcome.

But, starting at -6, we'd only need to count 6 to the left two times, not three times.

Or starting a 0 count 6 to the left three times.

To model the multiplication of -6 and 3 on a number line, you need to understand the concept of multiplication and how it relates to the number line.

1. Start by drawing a number line with negative and positive numbers. Place a zero (0) in the middle.

... -4 -3 -2 -1 0 1 2 3 4 ...

2. Since we are multiplying -6 and 3, we have one negative number and one positive number.

3. Begin at zero on the number line, representing the multiplication starting point.

4. Locate -6 on the number line. To do this, count 6 units to the left of zero. The position will be -6.

... -4 -3 -2 -1 0 1 2 3 4 ...

5. Now, move in the positive direction by multiplying 3.

6. To account for the positive multiplication, move 3 units to the right from -6.

... -4 -3 -2 -1 0 1 2 3 4 ...

7. Continue counting and mark the final position. The final value represents -6 multiplied by 3.

... -4 -3 -2 -1 0 1 2 3 4 ...

8. The final value on the number line is 18, indicating that -6 multiplied by 3 gives -18.

By following these steps, you can model the multiplication of -6 and 3 on a number line and see the result visually.
