Prerequisites Mathematical language Pedagogical notes Reflect a in a vertical line of symmetry Symmetry Pupils should be able to identify a mirror line at 45°, but not to use one Use a ruler to construct a straight line joining two points to carry out a reflection. Line of symmetry, Mirror line Know the of special quadrilaterals Isosceles legs’ ‘equal Reflect, Reflection Encourage pupils to draw irregular polygons, especially hexagons, Congruent pentagons, octagons and decagons Perpendicular, Parallel NCETM: Vertex (Vertices) Side, Edge Useful resources: Sets of 2D and 3D shapes, polydron, mirrors, pegboards, pinboards, rulers, dot isometric 2-D shape dice, string Quadrilateral Square, Rectangle, Parallelogram, (Isosceles) Trapezium, Kite, Rhombus Common approaches Triangle classroom has a set of and on the wall Scalene, Isosceles, Equilateral Every classroom displays shapes in different orientations. Polygon, Hexagon, Pentagon, Octagon, Decagon Every classroom displays regular and irregular hexagons, pentagons, Circle octagons and decagons Notation Dash notation to represent lengths in shapes and geometric diagrams Right angle notation to indicate perpendicular lines Reasoning opportunities and probing questions Suggested activities Possible misconceptions
