They will be able to use rotational symmetry when describing a shape's properties. They will be taught to identify how many times a shape can be rotated around a centre point and remain the same. In Year 6 some more able children will also look at rotational symmetry (generally taught in Y7). The direction of the line of symmetry is not fixed and is flexible. Extension task is credit of TES user TristanJones. The second lesson is more advanced and features linear graphs as lines of symmetry. This is often combined with coordinates work. Reflection Symmetry - Maths A shape or figure can have one or more symmetric lines. Two lessons on reflection: An introduction which focuses on symmetry and reflecting simple shapes with a fully differentiated main task. They will be given a shape and asked to reflect in the other three quadrants using the x-axis and y-axis. The (capital) letters A, B, C, D, E, H, I, K, L, M, O, T, U, V, W, X and Y (depending on how you draw it) all have at least one plane of reflection symmetry.

The shape that has been reflected will be the same as the. Or they may be asked to reflect whole shapes in a mirror line. Reflective symmetry is where a shape or pattern is reflected in a mirror line or a line of symmetry. For example, they may be given half a shape and asked to complete it using the mirror line. In Year 5 children are taught to reflect shapes and patterns in lines that are parallel to the axis. They will often use squared paper to do this task.

They will become aware that shapes may have more than one line of symmetry and complete investigations about how many lines of symmetry shapes have.Ĭhildren will also learn to draw symmetrical patterns with respect to a specific line of symmetry.

In Year 4 children identify lines of symmetry in 2D shapes. In Year 3 children are taught to sort shapes into symmetrical and non-symmetrical polygons. They may be given the shapes and asked to fold them or draw on a line of symmetry. In Year 2 children will be introduced to the concept of symmetry and taught to identify line symmetry in a vertical line.
