Why do this problem?
It acts as a further extension to Great Squares
. It's an activity that is intended to give opportunities for those pupils to explore deeply using their intuition, flair and risk-taking skills.
As this is designed for the highest attaining, it might be presented as on the website or in a one-to-one situation, encouraging discussion between adult and pupil. It may well be that choosing just one of the five pictures and staying with that for a considerable investigational time is the best way to use the activity.
Tell me about this/your thinking.
