Position in the 1st Quadrant
Notes and Guidance
The children start with an understanding of the origin (0, 0), before moving onto reading other coordinates. (0,0) being centre of the x and y axis. Don’t forgot that coordinates are always written in brackets with the x axis first then the y.
They understand that the first number represents the 𝑥-coordinate and the second number represents the 𝑦-coordinate. A great easy trick for reading coordinates is that you always go along the corridor first (so the x axis to the correct point) and then up or down the stairs (so using the y axis afterwards).
For example, the coordinates (2,3). This would mean that you go along the x axis first to 2 and then the y axis second to 3, meeting on the line in the quadrant for the point.
Coordinate are fixed (does not move) whereas a point can be plotted at different coordinates, so it can be moved.
Which of the numbers represents the movement in the direction of the 𝑥-axis (from the origin)?
Which of the numbers represents the movement on the 𝑦-axis (from the origin)?
Does it matter which way around coordinates are written?
Look at the point I have marked, what are the coordinates of this point?
If I moved the point one place to the left, what would be different about the coordinates?
If I moved the point down one, what would be different about the coordinates?
