Symmetry in Shapes Lesson with Worksheets (Year 2/3)

Answer sheets provided. Full lesson with teaching input (powerpoint), 3 differentiated worksheets (HA is higher, MA is middle and LA is lower ability). One of the presentations is Word in case you want to edit it. Three extensions are provided looking at symmetry in capital letters in the alphabet, drawing own symmetrical shapes, symmetrical patterns and symmetry in a circle. A circle has an infinite amount of symmetrical lines. The circle symmetry and symmetrical patterns with squares are also the plenary. The circle had an infinite number of lines of symmetry as long as the lines are straight and go through the centre point. Note an oblong has 2 lines of symmetry in a cross pattern but NOT diagonal symmetry. Use rulers (see through better) to draw the lines of symmetry and mirrors to check if shapes have symmetry. If they do the mirror would create the exact original shape. When investigating symmetry in the triangle, square, pentagon and hexagon the pattern is the number of sides is equal to the number of line of symmetry. This can be prompted by telling children to rotate the shapes a little bit first. For the triangle and pentagon you have to start at each corner and go straight down into the middle of the line below.
