Area of Composite Shape-Critical thinking Activity-Math Challenge 1

AREA OF COMPOSITE SHAPE ACTIVITY

Math Challenge Activity- to keep your learners engaged, thinking critically and making connections to 2D shapes.

This activity requires learners to determine the area of a shape based on the given dimensions. It also encourages them to think creatively and come up with mathematical strategies to solve unknown lengths.

The aim of this activity is to:

• Increase their fluency and confidence in geometry and measurements

• Develop understanding of a variety of 2D shapes in real life problems.

In this activity, students will practice finding the area of a composite

(irregular) figure involving a rectangle, a triangle and semi-circles.

Step-by-step solutions are also included.

Grades: 6th to 9th

Learning Outcomes:

Establish the formulas for the areas of rectangles, triangles and
parallelograms, and use them in problem-solving.
Solve problems involving the area of circles.
Calculate the area of the composite shape.

Also comply with Australian Curriculum:
Calculate areas of composite shapes (ACMMG216)
