Objectives

Students will be able to measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), liters (l), and milliliters (ml).

Language

Students will be able to explain measurements and estimations of liquid volumes and masses of objects using sentence frames and key vocabulary.

Introduction

(3 minutes)
• Get students talking about some of the tiered vocabulary words to assess prior knowledge. Display the following words on the board: volume, mass, grams, kilograms, liters, milliliters, measure, estimate, unit.
• Split the class into small groups and have them choose one of the tiered words from the board. Give them one minute to discuss what they know about the word and any questions they have about it.
• Have groups share their knowledge and/or questions about their chosen word. Validate student responses and provide feedback as necessary.
• Share the language objective for the lesson and explain that students will be discussing measurements and the most appropriate unit to use. Explain that measurement is an important function in mathematics, but also in our everyday lives.
