Skills, knowledge and understanding		Example
Adults should be taught to:
9 .	work out the area of rectangles	Work out the floor area of a rectangular room. Work out the area of lawn to calculate how much grass seed is needed.
	know that area is a measure of surface
	know what measurements are required to calculate area, and how to obtain them
	know that measurements must be in the same units before calculating area
	know that the area of a rectangle = length x width
	know that area is measured in square units

Sample activities

Discuss reasons for finding areas, e.g. for items that are sold by the square metre or square yard (such as carpets), to estimate the amount of paint required to paint a wall (coverage is given on the tin).
Discuss the units of measure for area, e.g. square centimetre, square metre, square yard and the different ways to write them, e.g. cm². Decide which units are appropriate for different-sized areas.
Look at different ways of finding areas - by counting squares on drawings on squared paper, by drawing a plan and drawing in squares to scale.
Find areas of different rectangular shapes and from the results construct a formula in words to find the area of a rectangle.
Estimate, measure and calculate areas of different rectangular shapes, e.g. walls, table tops, floor areas, etc.
