Symmetry in shapes
Context
Students were asked to choose and collect selected shapes from a computer package and identify the lines of symmetry. Students were given the opportunity to check the lines by folding their cut-out shapes. These samples used the AutoShapes function in Microsoft ® Word.
The elements of the Space standard addressed by the task are:
(Students) recognise and describe symmetry, asymmetry … in … shapes …
Sample
The following sample illustrates the kinds of responses that students typically produce when they have achieved the elements of the standard addressed by the task.
1. Mark the line of symmetry on a shape that has ONLY one line of symmetry.
Use a blue pen or pencil to colour a shape that has NO lines of symmetry.
2. When it is your turn on the computer, choose another shape from AutoShapes (not the one you used in question 1) that has at least one line of symmetry. Insert it onto a blank page. Make your shape about half a page in size. Print the page.
Cut out the shape and find the lines of symmetry by folding the shape.
How many lines of symmetry did you find?
Draw the lines of symmetry on the cut-out shape and glue the shape in the space below.

This sample is also used in Working mathematically Level 3.
Annotation
Space – Level 2
- The student correctly identifies a shape with only one (vertical) line of symmetry and sketches this line on the shape. The student has also correctly identified a shape with no line of symmetry. They correctly identify all 5 lines of symmetry on the star.
