Students learn how to calculate the area of parallelograms and trapeziums by considering how a parallelogram can form a rectangle and a trapezium a rectangle and triangle. Using this knowledge they derive the formulae for their respective areas. As the lesson progresses there is opportunity to apply these formulae to calculate the areas.
Differentiated Learning Objectives
- All students should be able to calculate the area of a parallelogram using the formula
- Most students should be able to calculate the area of a parallelogram and trapezium using the formulae.
- Some students should be able to calculate the area of compound shapes involving parallelograms and trapeziums.
