Developed in partnership between AERO and Ochre Education, these lesson resources support the use of effective, evidence-based practices and address the learning expected in the Australian Curriculum. An exemplar unit plan provides guidance on the structure, sequence and decision-making made during the planning process.
This sequence of five lessons teaches students about perimeter and area of shapes, as well as how to calculate them.
Lesson 1 To calculate and measure perimeter
www.edresearch.edu.au/guides-resources/ochre-resources/year-5-maths-unit-3-lesson-1Students will learn to calculate perimeter in simple and compound shapes.
Lesson 2 To calculate the area of rectangles
www.edresearch.edu.au/guides-resources/ochre-resources/year-5-maths-unit-3-lesson-2Students will find the area of rectangles by counting squares and using arrays and multiplication. They will also compare the area of different rectangles, including squares.
Lesson 3 To calculate the area of basic compound shapes
www.edresearch.edu.au/guides-resources/ochre-resources/year-5-maths-unit-3-lesson-3Students will learn to calculate the area of basic compound (rectilinear) shapes by splitting them into two or more rectangles.
Lesson 4 To compare the area and perimeter of rectangles
www.edresearch.edu.au/guides-resources/ochre-resources/year-5-maths-unit-3-lesson-4Students will compare the area and perimeter of rectilinear shapes.
Lesson 5 To calculate the area of non-rectilinear shapes
www.edresearch.edu.au/guides-resources/ochre-resources/year-5-maths-unit-3-lesson-5Students will estimate the area of shapes that are not rectangles and are presented on a grid. Then they will use a mixture of calculating the area of rectangles and counting the additional parts to estimate the total area.
