Symmetry
Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...

Reflectional Symmetry And Rotational Symmetry
Fifth graders study reflectional symmetry and rotational symmetry. They go outside and explore symmetry in the environment. They come back inside and make symmetrical masks that represent their way of life.

Rotational Symmetry
Students practice how to draw a line of symmetry inside a shape. In this symmetry lesson plan, students record the sides, lines of symmetry, and order of rotational symmetry for different shapes.

Exploring Symmetry
Students use a software program to create artwork and to manipulate images to study mirror and rotational symmetry. They take pictures of items in their environment in which they identify symmetry.

Creating and Destroying Symmetry
Students study the types of symmetry that appear in different basketball symbols. They point out changes that rotate symmetry from one type to another.
Curated OER
Reflections of Symmetry
Students use video and the Internet to identify examples of bilateral and radial symmetry in the world around them. They create symmetrical reflection designs using pattern blocks and paper.

Symmetries of a Quadrilateral I
Learners examine the properties of quadrilaterals from the point of view of rigid motion. Different types of quadrilaterals are characterized by their symmetries, so learners explore the symmetries of a described quadrilateral to...
Curated OER
Symmetries of a Quadrilateral II
Learners investigate the symmetries of a convex quadrilateral in a collaborative activity. Rigid motion and complements are explored as learners analyze different cases of reflections across a line.
