Application Problem (10 minutes)
A school ordered 247 boxes of pencils. Each
box contains 100 pencils. If the pencils are to be
shared evenly amongst 10 classrooms, how
many pencils will each class receive? Draw a
place vlaue chart to show your thinking.

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.
