CoordinatesA self marking exercise on identifying and naming coordinates (Four quadrants). 
Each square on the grid represents one unit. Type your answers without spaces but remembering the brackets and the comma like this (3,4)
The black lines are the axes and they cross at the origin.
What are the coordinates of the purple point? 

What are the coordinates of the yellow point? 

What are the coordinates of the pink point? 

What are the coordinates of the orange point? 

What are the coordinates of the red point? 

What are the coordinates of the maroon point? 

What are the coordinates of the lime point? 

What are the coordinates of the green point? 

What are the coordinates of the brown point? 

What are the coordinates of the blue point?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

"I would just like to point out that in your section called "First Quadrant", which you advertised that it had questions that consisted of questions from the first quadrant, had questions that involved coordinates that were placed on the axis, which are not technically in the first quadrant. The class got very annoyed and would appreciate you changing this. Thank you."

"Thanks for your observation Max. If the first quadrant is the region where both the x and y coordinates are positive then any point on either of the axes should not be included as zero is not a positive number. You are absolutely right.
Having realised that I would like to suggest that the inclusion of points on the axes makes the exercise slightly more challenging and worthwhile. I hope you'll agree.
Now Levels 1 and 2 are purely first quadrant without zeros and Level 3 contains zeros and fractional coordinates.
Thanks again for your comments."

"Some people have trouble remembering what the two numbers in a set of coordinates represent. They could be thought of as the route to the point from the origin. The first number is the xcoordinate and tells you how many units you go across to the right (negative numbers move you to the left). The second number tells you how many to move up (negative numbers move you down).
The following saying helps you remember the order of the coordinates:
Along the corridor then up the stairs. "
