Area of Composite Shape-Critical thinking Activity-Math Challenge 2

AREA OF COMPOSITE SHAPES 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 circles and squares based on the given dimensions. It also encourages them to think creatively and come up with mathematical strategies to solve unknown lengths and compare the areas of circles and squares and shaded parts.

The aim of this activity is to:

• Increase their fluency and confidence in geometry and measurements
• Develop understanding of a variety of problems with 2D shapes.

Step-by-step solutions are also included.

Grades: 6th to 9th

Learning Outcomes:

• Solve problems involving the area of circles and squares.
• Calculate the area of composite shapes.
• Determine the ratio of square area to circle area.
• Determine the ratio of shaded areas.

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