This can be easily accomplished using a program such as Geogebra, but I would encourage some mental visualisation first and reasoning as to why this happens once established. Start by tracing the locus of one point (not necessarily a vertex) as it is transformed on the object to its corresponding position on the image. They offer an opportunity really to get to grips with the effects of rotating an object. Many of these tasks could, and I believe should, be investigated before the transformation is formalised. In doing so we equip students with a deeper resonance with the subject matter. Much of what I write below may seem obvious, but often what we believe is obvious needs explicitly discussing in class. In the case of transformations, inspecting the relationship between corresponding points really closely reveals a huge amount. I realise now the importance of thoroughly and utterly studying a single rotation, not only as a whole but also in minute detail. Yet now, approaching the content from a much more connected methodology initiated by my work here, I’m questioning the emphasis I put on practising carrying out and describing transformations.

So I felt pretty confident that I knew how to present and work through the topic. I don’t know about you but I’ve spent many years teaching rotations using plenty of practical equipment: large shapes to rotate on the board shapes on a bamboo cane to show how they rotate around a point jigsaw puzzles tracing paper and dynamic geometry packages and I even wrote a chapter on transformations for the CUP GCSE text book. It is further supported by considering the tasks and activities we ask pupils to carry out. Developing coherent learning sequences can be more time efficient and allow for a much greater depth of study. One reason I am here working at Cambridge Mathematics is I passionately feel that the Framework can support teachers in developing a more coherent, joined-up sense of mathematics, both for themselves and their students. Obviously this has serious consequences for our learners. Secondly, it showed how the nature of our curriculum really does compartmentalise content, potentially leading to disconnected schemes of work. Firstly, it highlighted how little geometry content there is within the KS4 English national curriculum. Recently I spent a wonderful couple of hours with Tom Button from MEI, considering the use of dynamic geometry and KS4 geometry content.

Recently I’ve been struck by the number of things I have taught without fully and completely recognising how they are connected, even what I considered relatively ‘simple’ concepts. Every week I learn something new at work.
