This Mathematics unit addresses the concept of measuring, comparing and ordering area using informal units.
It consists of 5 lessons of approximately 60 minutes duration.
The sequence of lessons and suggested time frames 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.
This unit plan includes the following resources:
- To introduce the concept of area and how it can be measured using informal units.
- To explore the concept of area and how it can be measured using informal square units.
- To measure the area of plane shapes using informal square units.
- To apply knowledge and understanding of area to a real-world context.
- To revise and consolidate the concept of area.
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 Area collection 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
Recognize area as an attribute of plane figures and understand concepts of area measurement.
A square with side length 1 unit, called "a unit square," is said to have "one square unit" of area, and can be used to measure area.
A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.
