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

AREA OF COMPOSITE SHAPE ACTIVITY

Maths 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.

Comply with Australian Curriculum:
