Giving rotational symmetry the ‘wow’ factor


This video is taken from the iTunes Visualiser called Jelly that makes pretty patterns that react in real time to the music that is playing. The patterns produced show rotational symmetry and could be used as an excellent resource in a starter or plenary on the topic.

Rotational symmetry- synchronised swimming


Further to our post “Symmetry the fun way: B-boy dancing“, Mr Williams suggested a great idea of using synchronised swimming as inspiration for a lesson about rotational symmetry.

Here is the Japanese Team in full flow at the Sydney Olympics:

There is an excellent routine at about 2 mins into the video which has some fantastic rotational symmetry in it. You could freeze frame the video here and use it to demonstrate the concept.

There are endless possibilities you could go on with from here: could they design their own synchronised swimming pattern/ routine and draw it or act it out on land, get them in the pool for a cross-curricular link if you have one or could they do some research for a homework to find as many pictures showing rotational symmetry in sports and other applications as they can? Great fun.
