Nov 13, 2020 · They are split into 2 sections: the first is aimed at children in year 2 and year 3 who have learned about symmetry in KS1 maths and the second is aimed at children in year 4 and above who have in addition studied the symmetry topics in KS2 maths.

- Activities For Your Classroom.
On the national curriculum, symmetry makes its appearance in year two, and it is practised throughout a student’s education. The learning outcome for students is that: 1. Students should be able to identify lines of symmetry in 2-D shapes and identify the properties of each shape including the number of sides and faces. 2. Students should also draw...
What is it?
The line where the shape is cut exactly in half. This means that if you were to cut the shape in half (using your line of symmetry) both halves would be equal. If you were then to place them back together, the shape would still be the same.
Why do we use it?
The line of symmetry is a fundamental part of geometry, the world, and shapes. As mentioned above, a line of symmetry aids with measuring in equal parts, but it also helps us identify how to rotate, translate, and reflect other shapes. Symmetry is in nature, but many people often do not recognise it, examples of symmetry in the world would be butterflies, flowers, feathers, some insects, animals, buildings.
In maths, especially geometry, a 2-D shapes stands for a two-dimensional shape. These shapes are flat, and only have two dimensions: length and width. 2-D shapes do not have any thickness and usually only have two faces.
Understanding symmetry can sometimes be a challenge for those students who are not “visual learners”. To help, Emile has come up with seven activities that might be useful for your classroom.
Watch the video below from BBC Bitesize KS2 Maths which shows the lines of symmetry on a square, triangle, rectangle and circle.
How many lines of symmetry does a parallelogram have? Correct answer: 0. 0. 1. 2. 4. Q6. How many lines of symmetry does the shape below have? 1. 2. Correct answer: 3 ...
This kind of symmetry can also be called reflective symmetry or reflection symmetry. Now look what happens when you fold the letter 'A' along different examples of dotted lines. Attempting symmetry
Look for examples of reflective symmetry in the children's environment and when learning about other subjects e.g. lines of symmetry in flags or famous landmarks. Use mirrors to explore lines of symmetry in different shapes and to support children when drawing reflections in a line of symmetry.

How do you know if a 2D shape is symmetrical?
A 2D shape is symmetrical if you draw a line through it and it looks exactly the same on either side of the line. Find out more in this KS1 Bitesize guide.
