This is an activity is well described and includes necessary graphic organizers and pictures to teach students symmetry, lines of symmetry and rotational symmetry. Navigation through the website is not intuitive (Lesson is found by selecting: Welcome, Numeracy, Exploring Shape and Space, Exploring Symmetry). Additionally, this activity would be more appropriate for upper elementary students. Overall, this activity can be easily incorporated into a classroom and would be a useful introduction to symmetry.

Symmetry is where a shape can be folded along an imaginary line so that opposite side of the shape matches or fits exactly on top of the other. When one half of the object is exactly the same as the other, it is called its mirror image.
The fold, which is created, is called a line of symmetry. The line of symmetry of an object can be vertical, horizontal, or both.
Symmetry is found all around us in nature, art, and man’s own designs.
