Mathematics - Learning about Coordinates

We had to draw a grid with a ruler and then label the horizontal and vertical axis. Next we drew our own deserted island drawing in the key physical features while using coordinates to identify exactly where these features were. Then our partners had to use these coordinates to find the physical features. Finally, we had to record these coordinates in our descriptive stories about being ship wrecked on the island. For example, at A:3 I found fresh water
