# Finding symmetry: two lines: garden

TLF ID L7799

Explore a secret garden to find shapes with one line of symmetry. Look for shapes that are hidden in objects, for example a pond, paving stone and park bench. Use the testing wand to fold the shapes into matching halves. Check your prediction. Find and test more hidden shapes. This learning object is one in a series of six objects.

#### Educational details

Key learning objectives
• Students distinguish between symmetrical and non-symmetrical 2D shapes.
• Students test a shape for reflectional symmetry by folding it into a matching half.
• Students analyse shapes with two axes of symmetry.
Educational value
• Demonstrates that a variety of 2D shapes have two lines of symmetry.
• Provides opportunities for students to test axes of symmetry using a shape-folding tool.
• Allows students to explore 2D shapes to develop an understanding of symmetry by folding them into matching halves in one or more different ways.
