Multiplication by Large Place Values and their Multiples (Part 1)

This lesson teaches how to multiply a single-digit whole number by a place value or its multiple. It explains that multiplying by place values like 10, 100, or 1,000 results in the original number followed by the same number of zeros as in the place value. Examples include multiplying 7 by 100 to get 700 and by 1,000 to get 7,000. The process involves multiplying the number by the digit 1 and appending the zeros from the place value.

What is the significance of the digit 1 in place values like 10, 100, and 1,000?

Explain how the number of zeros in the product relates to the place value.
