Coordinates (age 10+)
Describe positions on the full coordinate grid (all four quadrants); use coordinates with negative values
Lesson
Set out your lesson
“Coordinates (age 10+) means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Number line (−5 to 5) on paper
- A token
Extra for the adult
Worked example. On the number line, 3 is to the right of −2, so 3 is greater.
Optional challenge. For Coordinates (age 10+), add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Coordinates (age 10+), not mastery.

Check understanding
- Plot points with negative coordinates such as (−3, 4) and (2, −5) on a four-quadrant grid
- Identify the quadrant in which a given point lies
- Describe the position of a shape using coordinates in all four quadrants
“If your child is playing a game where ships can be at negative coordinates too, can they correctly plot and read positions like (−3, 2) or (1, −4) on a grid?”
