Symmetry
A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other.
The line is called a line of symmetry.
Why is symmetry helpful?
There are lots of reasons why symmetry is helpful. One of the most important is that symmetry creates balance. Our brains really like symmetrical things and are automatically drawn to it.
Another reason is that it makes things much easier to understand. Symmetrical objects are predictable, so we know what to expect, making them easier to remember.
Today the P3 children went searching for shapes with a line of symmetry. They found lots of interesting symmetrical shapes in and outside the school building.
