Introduction

(5 minutes)
Preparing to Convert Metric Measurement Using DeconstructionMetric Length Measurement: Word ProblemsMetric Mass and Volume Measurement in Word Problems
  • Pass out metric rulers, one per student.
  • Direct students to examine their rulers and note the size of the different units.
  • Prompt students to share with a partner the names for any units they know (like centimeters and millimeters) and examples of items they could measure with those units.
  • Pose the following question to your class: "How might you measure something using the metric system that is longer than a ruler, like their desk, the height of the door, or the distance to the grocery store?"

Beginning

  • Allow students to use their home language (L1) or new language (L2) in their discussions throughout the whole lesson, whether their speaking in partners or to the whole group.
  • Provide vocabulary cards with visuals if possible for the following words: "measurement," "nearest," "conversion," "centimeter," "meter," and "metric." Give them definitions in their L1 and L2.
  • Take notes of the ideas and metric units shared by students on the board with either a word web or another graphic organizer.

Intermediate

  • Write the academic language they can use throughout the lesson on the board as you introduce the language (e.g., "I would use meters to meaure ________.") and vocabulary terms (e.g., "centimeters," "metric," "meters," "millimeters," etc.).
  • Provide sentence stems to help students communicate their ideas, such as, "The length of the pen in meters is... A pattern I noticed is..."
