Year 8 – Measurement and Geometry

Screen Shot 2015-05-16 at 8.36.18 PM

National Curriculum Standards: Students convert between units of measurement for area and for volume. They find the perimeter and area of parallelograms, rhombuses and kites. Students name the features of circles, calculate circumference and area, and solve problems relating to the volume of prisms.

To calculate the volume of any prism, multiply the area of the base by the height (or in the case above, the trapezium by the length of the trailer). Make sure all the units are the same before starting your calculations.

Area of a Parallelogram and a Trapezium

trapezium table

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:
