Examples of what pupils should know and be able to do
Read and position the numbers on the axes accurately.
If three of the vertices of a square are (2, 1), (2, 4) and (5, 4), describe the coordinates of the fourth vertex.
Probing questions
I'm thinking of coordinates of a point that I want you to plot. I can only answer 'yes' and 'no'. Ask me some questions to find out the coordinate so that you can plot it.
How do you use the scales on the axes to help you read the coordinates of a point that has been plotted?
How do you use the scales on the axes to help you to plot a point accurately from its coordinates?
What if pupils find this a barrier?
