Learning Intention: You will learn the information required and how to calculate the area of two different quadrilaterals – parallelograms and trapeziums.
Success Criteria: Given sufficient information you will be able to work out the area of a trapezium and a parallelogram.
You know how to calculate the area of squares, rectangles and triangles. Can you use this information to calculate the area of a parallelogram? We will be doing two activities from your text book:
- Area of a Parallelogram (page 311). Then do Exercise 8D (page 313)
- Area of a trapezium (page 319). Then do Exercise 8F (page 321)
- Make sure you can identify the different types of quadrilaterals at Math Playground with the “Matching Game”.
- XP Maths has a game to find the area of parallelograms.
- Use an interactive parallelogram at Maths Warehouse.
- Properties of parallelograms at Cool.math.
