What is it?
When it comes recapping key topics we al know that practise makes perfect, but it means that sometimes pupils can end up working on autopilot. So, say hello to this resource, packed full of what I call ‘same surface, different deep' (SSDD) questions that are designed to prevent just that.
The premise is simple. Students are presented with four similar looking problems that they must solve, but, as always, there's a twist! Despite looking the same on the surface, each question asks for a different calculation, forcing them to think carefully about their choice of method. As they encourage pupils to identify topics and question types in isolation, these problems are perfect for ensuring that your learners' brains remain switched on.
How can it be used?
I’d suggest using these problems as part of a revision lesson with your GCSE students, as they are ideal for kick-starting discussions.
Alternatively, why not set these sheets as part of a homework task, or a low-stakes test? With the potential to cover so many different topics, the SSDD revolution starts here!
