Congruent shapes and objects by matching
Identify congruent side lengths, angles and faces by matching them physically (tracing, overlaying, folding, comparing with a strip, fitting faces together) or mentally, within and between two-dimensional shapes and three-dimensional objects, and decide whether two shapes or two objects are congruent: the same size and the same shape, whatever their position or orientation (matching one face alone does not make two objects congruent)
Lesson
Set out your lesson
“Congruent shapes and objects by matching 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 Congruent shapes and objects by matching, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Congruent shapes and objects by matching, not mastery.

Check understanding
- Find the sides of equal length and the matching angles within a shape (e.g. a rectangle's opposite sides and four corners), and trace one shape onto another to decide whether every side and angle matches, explaining why a turned copy is congruent but a larger one is not
- Match the faces, edges and corner angles of two 3-D models (e.g. two boxes or two prisms) by tracing faces or fitting them together, and say which faces, edges and angles are congruent
- Decide whether two 3-D objects are congruent by checking that all corresponding faces match and are arranged the same way, explaining why two boxes with the same front face but different depths are not congruent
“If your child has two boxes or two paper shapes, can they match the sides, corners and faces to check whether they are exactly the same size and shape — and notice when two boxes look the same from the front but are not?”
