Real Life Maths Examples

« Go back

Area is one of the most difficult Measurement sub-strands for your students to understand. We use spatial visualisation skills to estimate areas large or small.  Areas include surface areas which can be curved and squiggly and difficult to think about. Area calculations also require skills iusing decimal operations (+ – x ÷). And when we talk about Area with our students, we need to use real life examples so that our students deepen their concepts of how area works in the world around them. It can’t be taught as just conversion facts and figures (e.g. How many square metres in a 2 x 12 rectangle?)

This old photo shows a man painting the Eiffel Tower. The total area of metal struts and surfaces that need to be painted regularly is about 250000 square meters. One litre of paint covers about 16 square metres. If the maintenance team need to give the Eiffel Tower 2 coats, how many litres do they need? How many tonnes of paint is that? If bulk paint works out at $5 per litre, how much does just the paint cost? The whole upkeep must be so expensive.

Photographs are a great way to springboard your lesson into real life.
