Symmetry We are learning to: Identify line symmetry in shapes and in the environment. Day One Look at the example below.


Where could you draw a line and fold this shape so that it will fold over exactly onto itself?


Circle the numbers and keywords: shape, fold over exactly onto itself


Link with operation needed (+ or −): None Keyword


A shape or an object is symmetrical when one half can be folded


over evenly onto another half.


Use a strategy: Make a model. Draw the shape. Cut it out and try folding it exactly in half.


Estimate and calculate: It folds exactly here.


This is a line of symmetry.


Summarise how you got your answer: I used my ruler to draw a line where the shape folded over exactly onto itself.
