Click here for the GTEN workshop video that follows the development of concepts of reflection, rotation and symmetry from looking at your own hands in Year 1, to observing both rotational and reflection symmetry in nature, making symmetric patterns by folding and cutting paper, solving puzzles involving symmetric patterns, then reflections in parallel and intersecting mirrors, understanding that symmetry groups have applications in christallography and particle physics.
