Multiplication by Large Place Values and their Multiples (Part 2)

The video tutorial explains how to multiply a single-digit number by a multiple of a place value. It demonstrates this with examples, such as multiplying 5 by 500 and 2 by 50,000. The key is to multiply the non-zero digits and then append the zeros from the place value. This method works for any place value and its multiples.

What is the first step when multiplying a number by a multiple of a place value, such as 5 times 500?

• Divide the numbers by 10.

• Subtract the smaller number from the larger one.

• Multiply the numbers as if there are no zeros.

• Add the numbers together.

After multiplying the non-zero digits in 5 times 500, what should you do next?

• Add zeros to the left of the result.

• Multiply the result by 10.

• Subtract the result from 1000.

• Add the zeros back to the right of the result.

In the example of 2 times 50,000, what is the product of the non-zero digits?

• 5

• 10

• 15

• 20

How many zeros are added to the right of the product in the example of 2 times 50,000?

• Five

• Four

• Three

• Two

What is the general rule for multiplying a single-digit number by a place value?

• Divide the result by the number of zeros.

• Always add one to the result.

• Multiply the numbers and then add the zeros back.

• Subtract the smaller number from the larger one.
