Lines of Symmetry Monday 20th April
Lines ofSymmetry Activity 1 Find one line of symmetry in these shapes. ? Explain what you understand by the term symmetrical . 4 Properties of Shapes 2
Lines ofSymmetry Activity 1 Using folding, find the lines of symmetry in these shapes. 4 Properties of Shapes 3
Lines ofSymmetry Activity 2 Sort the shapes into the table. 1 line of symmetry More than 1 line of symmetry Up to 4 sides More than 4 sides ? How can you tell if somethingis symmetrical? 4 Properties of Shapes 4

Lines ofSymmetry Activity 3 Draw the lines of symmetry in these shapes (you could use folding to help you). What do you notice? ? Are lines of symmetry alwaysvertical? 4 Properties of Shapes 8

Lines ofSymmetry Reasoning1 How many symmetrical shapes can you make by colouring in a maximum of foursquares? 4 Properties of Shapes 10
Lines ofSymmetry Reasoning1 How many symmetrical shapes can you make by colouring in a maximum of foursquares? There are a variety of options. Some examplesinclude: 4 Properties of Shapes 11
Lines ofSymmetry Reasoning2 A triangle has one line of symmetry unless you changetheorientation. Zach Is Zach correct? Prove it. 4 Properties of Shapes 12
Lines ofSymmetry Reasoning2 A triangle has one line of symmetry unless you change theorientation. Zach Zach is incorrect. A triangle may have one or three lines of symmetry depending on its nature. Changing the orientation does not change the lines of symmetry. Children should prove this by drawing shapes in different orientations and identifying the number of lines ofsymmetry. 4 Properties of Shapes 13
Lines ofSymmetry Reasoning3 Always, Sometimes, Never? A four-sided shape has four lines of symmetry. 4 Properties of Shapes 14
Lines ofSymmetry Reasoning3 Always, Sometimes, Never? A four-sided shape has four lines of symmetry. Sometimes, provided that the shape is a square or a rhombus. 4 Properties of Shapes 15
Lines ofSymmetry Discussion Explain what you understand by the term symmetrical . Can you give any real-lifeexamples? How can you tell if something is symmetrical? Are lines of symmetry always vertical? Does the orientation of the shape affect the lines of symmetry? What equipment could you use to help you find and identify lines ofsymmetry? What would the rest of the shape look like? 4 Properties of Shapes 16
