- Examples of what pupils should
know and be able to do - Probing questions

this a barrier?
What if pupils find this a barrier?
Refer to Step 6.
Choose some equations that are typically causing problems. Ask pupils to 'read' the information given to them in the equation. Use dialogue to expose the nature of the misconception.
Provide a range of equations for pupils to classify and solve in pairs.
This kind of activity can usefully be followed up with approaches like
annotate written solutions from TMM
