#### Learning Objectives

Students will be able to convert decimals to fractions in denominations of 10 or 100.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

#### Introduction

(5 minutes)
• Measure a pen to the nearest centimeter (a metric fractional unit of length = 100th of a meter) in front of your class. Highlight how to begin measuring with a ruler at zero, not one.
• Have a student write the measurement amount where the whole class can see it. (An average pen is about 30 to 40 cm.)
• Next to the answer, write the following conversion, from centimeters to meters (the standard unit for measuring length in the metric system):
• 10 centimeters = 0.10 meter
• 0.10 meter = 10/100 meter
• Referencing the conversion information, tell your students to think, pair, and share their thoughts on how long the pen would be in meters (expressing any patterns, clues, or observations).
• Have students share out their ideas. Encourage your class to use patterns, clues, or observations in their explanations.

Beginning

• Define the words "measurement," "nearest," "conversion," "centimeter," "meter," and "metric" in students' home languages (L1) and English (L2), and provide images and examples when possible.
• Pair beginning ELs with sympathetic partners or more advanced students for the think-pair-share.

Intermediate

• Have students rephrase the key points from the introduction first to a partner, then to the whole group.
• Provide sentence stems to help students do the think-pair-share, such as: "The length of the pen in meters is... A pattern I noticed is..."
