| A PowerPoint presentation with some interactive slides. there is an accompanying activity sheet in which children investigate what happens to the number of lines of symmetry when you combine two shapes, e.g. a square has four lines of symmetry, but when two are placed together you get a rectangle which has only two lines of symmetry. |

Solving problems
Make and investigate a general statement about familiar shapes.
SSM
Make shapes and discuss properties such as lines of symmetry. |

Can children identify the number of lines of symmetry in a shape?
Can children appreciate that combining identical shapes affects the numbers of lines of symmetry? |
| |
Children should understand line symmetry.
They should know that different shapes may have different numbers of lines of symmetry. |
| |
Children should be able to identify the number of lines of symmetry in given shapes.
They should be able to carry out an investigation using shape. |

 Symmetry investigation
- A PowerPoint presentation with some interactivity.
 Children's activity
- Investigate what happens to line symmetry when you combine two identical shapes.
Children's activity Sort the shapes
- Some shapes, regular and irregular for children to use in the Carroll diagram activity.
Carroll diagram, children's activity
- Children sort regular and irregular shapes into a Carroll diagram. They should identify that regular shapes all have lines of symmetry. This will provide a foundation for Year 5 work where they learn that the number of axes of symmetry equates to the number of sides in a regular 2D shape.
Shape sheet
- Children cut out the shapes, identify lines of symmetry and stick on the Venn diagram
Venn diagram simple
- For use with the shape sheet. This diagram shows the universal set of 2D shapes with a subset of shapes with one or more lines of symmetry.
Venn diagram complex
- In this diagram the set of shapes with lines of symmetry has a subset for those with two or more lines of symmetry.
