Coordinate Transformations
Identify properties of translations, rotations, and reflections; describe and perform these transformations on given figures, and understand that the image is congruent to the original
Lesson
Set out your lesson
“Coordinate Transformations 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
- Paper shapes or a ruler and pencil
- Shape or angle name cards
Extra for the adult
Worked example. A rectangle has four right angles. Naming the property is the check.
Optional challenge. For Coordinate Transformations, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Coordinate Transformations, not mastery.

Check understanding
- Reflect a shape in a given mirror line (including diagonal lines) and state the coordinates of the image
- Rotate a shape about a given centre by 90° or 180° and describe the result
- Translate a shape by a given vector and verify that lengths and angles are preserved
“If your child is asked to rotate a triangle 90° clockwise around a fixed point, can they work out where each corner ends up — and confirm the triangle is still the same size and shape?”
