### Coordinate Tan

What are the coordinates of the coloured dots that mark out the tangram? Try changing the position of the origin. What happens to the coordinates now?

### A Cartesian Puzzle

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

### Criss Cross Quiz

Little Ming: Together, decide where to place the origin (0,0). It can be on any of the points on the board.

Little Fung: Next, choose who will be blue and who will be red.

Little Ming: Blue goes first and chooses a point. Blue has to write down the coordinates of the point in relation to the origin.

Little Fung: If you get the coordinates of the point wrong, you don't get that point.

Little Ming: And it becomes Red's go.

Little Fung: Red chooses a point and gives its coordinates.

Little Ming: You then take it turns to go...

Little Fung: ...Until one person has four dots in line of their colour!
