Teaching Rotational Symmetry

4th grade students learn the term "rotational symmetry" in their math class, so for a cross curriculum connection we do a series of projects involving rotational symmetry. In this project students used a compass to draw perfect concentric circles in which they drew small pictures or patterns that rotated around the circle.

Students will identify the line and rotational symmetry of two-dimensional shapes. Investigate where those shapes can be folded or cut.

Teaching lesson notes are provided here. There are three types of symmetries that a shape can have: line symmetry, rotation symmetry and point symmetry. A geometric figure has rotational symmetry if the figure is the image of itself under a rotation about a point through any angle whose measure is strictly between 0°.

A geometric object has symmetry if there is an "operation" or "transformation that maps the figure/object onto itself; i.e., it is said that the object has an invariance under the transform. For instance, a circle rotated about its center will have the same shape and size as the original circle—all points before and after the transform.

rotation pattern. Did you notice any symmetry in the image? Does this help you to imagine how the image was made? Here is a diagram which shows how we created the image. We started with a triangle (shaded) and then used the coordinate grid to help us to rotate it through multiples of around the point. how to make a.

In order for a tessellation to be considered as having rotational symmetry it must represent the exactly same tessellation as the original after it has been rotated. If the tessellation does in fact show the same result as the original after it has been rotated, then it can be considered to be a tessellation with rotational symmetry.
