Joined-up conceptualisation

Watch the video

Here are brief reports of three parallel lessons about loci for Year 7 all-attainment groups that were planned together but ended up different. I leave a lot to your interpretation but the point is to notice the language that is used, the way tools are used and the order of tasks. These could lead to different ways to build an understanding of loci. You could go deep and consider how your own conceptualisation of loci could be authentically presented to learners through the tasks, or you could react in a more immediate way about whether you would, or would not, have done what they did.
