Mathematics in Everyday Life

It is sometimes difficult for students to appreciate the importance of Mathematics. They often find the subject boring and hard to understand. With this project we will hopefully help our students realise that Mathematics is not just a subject on their time-table but a tool they use in their everyday life!

Symmetrical Nature !

The Word Symmetry is often used in everyday language, and usually by people of all ages can recognise symmetry when they see it.
Symmetry in nature is most often Bilateral symmetry. This means that the two halves of an object are exact mirror images of each other.

Symmetry In the Animal Kingdom…

… in humans- the human face also has a line of symmetry in some places, but some faces are more symmetrical than others. There are also other examples of symmetry in the human body like the kidneys, lungs and the brain. This applies to most animals in the animal kingdom.

Symmetry In Plants...

… in flowers there are roughly identical petals, sepals, stamens and leaves.

Symmetry at the Beach…

… at the beach there are a variety of shells and underwater life with a line of symmetry, an example of which is a crab or a starfish.

There is also another type of symmetry called reflectional symmetry as the two parts match along each side of the waterline.
