Students will be required to dig down and find the buried metals at 5 specific points. Similar to battleships. Once they have found all of the treasure they're going to write down the co-ordinates.
Following on from this activity, pupils will create their own maps with their own treasure. They will get their friends to find the treasure and they will need to write down the co-ordinates of the metals. Once they've done this they are required translate the shapes by 1 or 2 so that they can move the treasure to a new location.
