Reflective symmetry seems to be a very popular topic for the Key Stage 2 Maths SAT Papers and it is not easy to find examples of the kind of question which is often asked. There are several mathematical terms to do with symmetry that children need to be familiar with. These include:
Mirror line, line of symmetry, line symmetry, symmetrical, reflect, reflection, translation, axis of symmetry, reflective symmetry.
Also they should be able to test for symmetry using a mirror and by folding.
Children should be able to sketch the reflection of a simple shape in a mirror line where none or only some of the edges of the shape are parallel or perpendicular to the mirror line.
This might seem easy, but actuallyoften proves to be problematic to many children. A small mirror is a great help with this and children are supplied with one in their SAT tests if such a question comes up.
Here we have the second of a pair of worksheets which looks at sketching the reflection of shapes in the mirror lines.
