Topic: Symmetry
Marcus du Sautoy on Symmetry
TED talk on Symmetry – 18 mins. Exploration of rotational symmetry using Alhambra tile patterns, and an insight in the history and human story of mathematics. Some advanced concepts but good for extending a class.
Rotational Symmetry
Click the play button to watch the shape rotate 360 degrees. As it turns, count how many times it fits back onto itself (bottom box) to give its order of rotation (top box).After seeing the first couple, a class should be able to do the rest on their own, possibly as a test. Currently contains 14 shapes.
Transtar - Mangahigh
In this maths game your aim is to guide the alien entity TranStar across the cosmos as it searches for the mysterious Core. By calling upon the awesome power of exotic space phenomena you apply transformations to TranStar, allowing you to reflect, rotate, translate and even enlarge it. But think carefully – one false move and TranStar’s star trek could come to a tragic end!
