This Mathematics unit addresses the concept of measuring, comparing and ordering volume using informal units.

It consists of 5 lessons of approximately 60 minutes duration.

The sequence of lessons and suggested time framesย should be regarded as a guide only; teachers should pace lessons in accordance with the individual learning needs of their class.

An assessment task for monitoring student understanding of the unit objectives is included and will require an additional lesson.

### Overview

#### Objectives

• To explore the concept of volume by comparing and ordering objects.
• To measure volumes of 3D objects using informal units.
• To estimate and measure the volume of objects using informal units.
• To apply knowledge and understanding of volume to a real-world context.
• To revise and consolidate the concept of volume.

#### Preparing for Learning

Prior to commencing the unit, create a measurement display in your classroom. Display teaching resources in the classroom that will stimulate the students’ interest and assist in their learning. For examples of teaching resources to display in your classroom, browse the Volume Collectionย on the Teach Starter website.

Some of the resources which accompany this unit plan will need to be prepared prior to teaching. For this reason, it is advised that teachers browse through all lessons before commencing the unit.

#### Common Core Curriculum alignment

• CCSS.MATH.CONTENT.5.MD.C.3

Recognize volume as an attribute of solid figures and understand concepts of volume measurement.

• CCSS.MATH.CONTENT.5.MD.C.3.A

A cube with side length 1 unit, called a "unit cube," is said to have "one cubic unit" of volume, and can be used to measure volume.

• CCSS.MATH.CONTENT.5.MD.C.3.B

A solid figure which can be packed without gaps or overlaps using n unit cubes is said to have a volume of n cubic units.
