Symmetry

Today, we started on a new unit on Symmetry. I started on Symmetry first as I believed it is an interesting new topic and being back from one week holiday, pupils will be more motivated to learn something new. Furthermore, it is faster to finish the topic as compared to other topics. The unit on Time will be covered after Symmetry and Tessellation as it is a more familiar topic to the pupils.

For Symmetry, we learnt about the definitions of symmetric figures and the line of symmetry.

Symmetric figures are figures when folded into half, the two halves matched or they are mirror-imaged.

The halves along the line of symmetry are mirror-images of each other. The line of symmetry is usually drawn with a dotted line and it is drawn with a ruler.

Below are the objects that we discussed in class where pupils were asked to categorise whether they are symmetric or non-symmetric objects.

It is important to take note that every aspect of the two halves must matched to be a symmetric object. For example, the leaf shown above looks symmetric, however when it is folded into half, pupils realised that the stalk is not symmetrical although the leaves are. 

The take home assignment for today is Unit 4 Activity 1 and to be submitted on Wednesday 10th September 2012.

Note: Parents can assist pupils in completing question 4 where pupils are expected to find cut-outs of objects which are symmetrical in newspapers and magazines.


Thank you.
