Why do this problem?
is one in which learners will be practising the use of coordinates and in addition will be developing their understanding of properties of shapes. The problem may challenge their preconceptions of how a shape "should be" oriented!
A similar activity could be set up practically in the classroom or outside using a floor turtle. In any case squared paper should be provided.
Would it help to draw out what Fred is doing on squared paper?
Have you counted the number of sides of each shape and looked at the angles?
What makes the shape a square and not another four-sided shape?
Learners could make their own shapes on squared paper and write down the coordinates.
Suggest drawing the shapes on squared paper. Moving the paper around might help in seeing what each shape is.
