Module 1 Lesson 2
Common Core
Standards
•
5.NBT.1 Recognize that in a multi-digit number, a digit in one place
represents 10 times as much as it represents in the place to its right and
1/10 of what it represents in the place to its left.
•
5.NBT.2 Explain patterns in the number of zeros of the product when
multiplying a number by powers of 10, and explain patterns in the
placement of the decimal point when a decimal is multiplied or divided by
a power of 10. Use whole-number exponents to denote powers of 10.
• 5.MD.1 Convert among different-sized standard measurement units
within a given measurement system (e.g., convert 5 cm to 0.05 m), and
use these conversions in solving multi-step, real world problems.
Learning Targets

A school district 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? Use a place value
chart to show your thinking.

Teamwork
Turn and share with your partner.
What do you remember about how adjacent
units on the place value chart are related?
Learn
•
Moving one position to the left of the
place value chart makes units 10
times larger.
• Moving one position to the right makes
units 1/10 the size.
