Area of 2D Shapes-Critical thinking Activity-Maths Challenge 3

AREA OF 2D SHAPES ACTIVITY

Maths Challenge Activity- to keep your learners engaged, thinking critically and making connections to 2D shapes. This activity requires learners to

• Determine which shape has complete dimensions to calculate its area

• Calculate the area of the other shapes including their type.

• Find the exact value of each pronumeral.

The activity encourages them to think creatively and come up with mathematical strategies to solve unknown lengths.

The aims of this activity are 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 2D Shapes.
• Find the unknown lengths (Critical Thinking)
