              Reflective symmetry in 2D shapes

              Students learn how to describe reflective symmetry in 2D shapes using mirror lines.  Learning progresses from finding the lines of symmetry in simple polygons to reflecting shapes in diagonal mirror lines.The start of the lesson recaps identifying the properties of quadrilaterals using coordinates in the first quadrant.  In the plenary students are challenged to create a series of quadrilaterals with different reflective symmetries when three vertices are fixed.
              Differentiated Learning Objectives
              • All students should be able to identify lines of symmetry in 2D shapes.
              • Most students should be able to describe and sketch polygons that are reflectively symmetric.
              • Some students should be able to describe and sketch 2D shapes that are reflectively symmetric.
