About this resource
Explore reflection symmetry with fifteen pictured flags, then design flags in two spaces with vertical and horizontal guide lines. This two-page PDF activity supports identifying symmetry and constructing a design with a specified symmetry line.
Compare colours, shapes and small details on both sides of each proposed line. No PowerPoint presentation is included in the supplied download.

Teaching tips & learning objectives
Learning objectives
- Test a design for reflection symmetry
- Draw supported lines of symmetry
- Create a flag design with a specified symmetry line
Teaching tips
- Trace a possible dividing line through each flag before comparing the two sides.
- Use the stripes and central shapes as reference points when testing whether the halves match.
Skills covered
- Symmetry recognition — pupils inspect flags for matching halves.
- Geometric comparison — stripes and shapes are compared across a dividing line.
- Visual reasoning — pupils judge whether a design remains balanced under reflection.
