Here is a treasure map.

What are the co-ordinates of these objects?

Write down what you can see at the co-ordinates given below:

- ($7, 5$)
- ($9, 5$)
- ($5, 3$)
- ($2, 3$)
- ($7, 1$)
- ($3, 3$)
- ($4, 2$)
- ($1, 1$)

The words can be used in a special way to find the coordinates of the buried treasure. Can you work out where it is?

Freddie Frog visits as many of the leaves as he can on the way to see Sammy Snail but only visits each lily leaf once. Which is the best way for him to go?

Find the missing coordinates which will form these eight quadrilaterals. These coordinates themselves will then form a shape with rotational and line symmetry.

What are the coordinates of this shape after it has been transformed in the ways described? Compare these with the original coordinates. What do you notice about the numbers?
