Translating and reflecting shapes
Draw and translate simple shapes on the coordinate plane; reflect shapes in the axes
Lesson
Set out your lesson
“Translating and reflecting shapes 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 name cards
Extra for the adult
Worked example. A rectangle has four right angles. Naming the property is the check.
Optional challenge. For Translating and reflecting shapes, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Translating and reflecting shapes, not mastery.

Check understanding
- Translate a triangle 3 units right and 2 units down on a coordinate grid and state the new coordinates
- Reflect a shape in the x-axis and list the coordinates of the reflected vertices
- Explain how translation changes coordinates (add/subtract) while reflection changes the sign of one coordinate
“If your child draws a triangle at coordinates (1, 2), (3, 2), and (2, 4) on a grid, can they then reflect it across the x-axis and tell you the new coordinates of each corner?”
