A worked example

One question of the kind this skill is tested with, worked all the way through: the reasoning, and what the wrong answers are there to catch.

Writing a point as a pair of coordinates

What are the coordinates of point B?

Follow the x-axis to 6, then the y-axis to 1.

-6-4-2246-6-4-2246OB

Coordinate grid from -6 to 6 on x and -6 to 6 on y. Points: B at (6, 1) .

Plotted on the grid: B at (6, 1).

  1. (6, -1)
  2. (1, 6)
  3. (6, 1)
  4. (-6, 1)

Answer: (6, 1)

How you get there

B is 6 right of the origin and 1 above it, so point B is written (6, 1). Writing (1, 6) instead would describe a different place on the grid, because the across number always comes first.

Why the other answers tempt

Counting squares from the origin gives the distance, but the sign says which side of the axis the point is on.

If they are stuck, say this

Read across the x-axis first and then up or down the y-axis - the first number in the pair is always the across one.

Now do it live in Coordinate Plotter

What this exercise is doing

Coordinate Plotter

Plot each labelled point on the grid. Read the horizontal coordinate first.

Coordinates give a position. The first number gives the horizontal position. The second gives the vertical position. Plot the point where those two grid lines meet.

What to say if they get stuck

  1. Start at (0, 0). Move across for the first number.
  2. Move up or down for the second number, then plot the point.

Open Coordinate Plotter on its own page to share it

What usually goes wrong here

  • Reads the vertical coordinate before the horizontal coordinate.

This is the wrong answer 11+ papers are built to offer, so it is worth watching for directly: a child who does this will look confident and still lose the mark. If it keeps happening on plot or read a coordinate, the fix is the misunderstanding rather than more questions.
