Reflections of Symmetry
Young scholars 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.
Curated OER
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.
Curated OER
Symmetry Monsters
Young scholars discuss and study the word symmetry. They examine letters of the alphabet, shapes, and artwork and decide if they are symmetrical or not. Then they create their own symmetry monsters.
Curated OER
Let's Learn about Symmetry
Students explore symmetry in architecture. In this cross curriculum art and architecture lesson, students fold paper to illustrate symmetry and identify symmetrical and asymmetrical shapes. Students observe photographs or take a walk...
Curated OER
Symmetry in My World
Second graders demonstrate understanding of symmetry and identify objects that have symmetry. They use a mirror to get a visual illustration of what symmetry is. They create a collage of symmetrical pictures they find in magazines.
Curated OER
Equilateral Triangle Symmetries Closure Activity
Students explore the symmetries of an equilateral triangle. For this lesson on symmetry, students determine the composition of given equilateral triangles using both rotational and reflectional symmetries.
Curated OER
Parallel and Perpendicular Lines
Fourth graders create a dance with a partner that shows parallel and perpendicular lines. In this lines lesson plan, 4th graders create symmetrical designs and line pairs with their partner.
Curated OER
Symmetry in Shapes and Everyday Objects
Fifth graders discover lines of symmetry for shapes and everyday objects. In this lines of symmetry lesson, 5th graders use a butterfly outline to find lines of symmetry. Students analyze everyday objects for symmetry and use...
Curated OER
Math Lesson: Rotational Symmetry
Students analyze lines of symmetry and rotational symmetry in designs. They practice dividing a shape along its line(s) of symmetry and discuss the relationship between lines of symmetry and number of sides as well as rotations.
Curated OER
Math: Symmetry and Similarity
Pupils describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist ties,...
Curated OER
Shape and Space: Symmetry
Students discuss and work with lines of symmetry. In this symmetry lesson, students start with a warm up activity on metric conversion. They talk about the definition of symmetry and reflection before completing a worksheet.
Curated OER
Symmetry in Kaleidoscope Designs
Students define reflection, rotation and symmetry. In this symmetry lesson, students move the graph around the coordinate plane and identify the line of symmetry. They identify the different designs of a kaleidoscope.
