You are to make a treasure map using recognised Ordnance Survey Symbols to allow authorised treasurer seekers find your hidden treasure. The map should include a beach/port for the treasurer seekers to land.
You are then to write a set of instructions for the for the treasurer seekers to follow. The best set of instructions is one where the treasurer seeker has to follow each step in order to find the treasure.
Treasurer seekers should be able to successfully trace the correct route across your treasure island from your beach/port to your treasurer.
