Student Debrief (10 minutes) When solving #2, how did the number of zeros in the factors help you determine the product? Compare and contrast answers in #1 a and b or c and d. Can you think of a time when there will be a different number of zeros in the factors and the product? What's similar about the process you used to solve #1 a, c, e and g? When dividing by 10, what happens to the digits in the quotient? When multiplying by 100, what happens to the places in the product What's similar about the process you used to solve #1 b, d, f and h? When asked to find the number 1 tenth as large as another number, what operation would you use? Explain how you know.
