Using Symmetry to Create Corporate Logos
Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the alphabet and...

Identifying Lines of Symmetry and Creating Reflections over a Line
Fifth graders review the concept of a line of symmetry by using pieces of paper that have pictures such as, letters of the alphabet, polygons, and designs made from polygons in order to determine if they have symmetry. The fine, two-hour...
Curated OER
Lines of Symmetry
In this math activity, middle schoolers practice drawing the lines of symmetry for each of the polygons. They also draw mirror images for the figures.

An Astronaut in Motion
How do you model the movement of an astronaut? The activity features software that uses an avatar to mimic movement. Groups work to determine the translation between the pre-image and the image. They then experiment with reflections in...

Line Symmetry
Teach your class about symmetry lines with this resource. This worksheet defines symmetry and explains lines of symmetry and how they work. Learners examine a variety of examples before drawing lines of symmetry in 5 figures. The...
Curated OER
Lines of Symmetry
Fourth graders demonstrate lines of symmetry using polygons, pentominoes, and block letters of the alphabet. They describe, identify, and analyze characteristics and properties of geometric shapes.
Curated OER
Matching Directions
These abstract shapes are pointing in different directions and young scholars determine which ones are oriented the same way. For each of five starting shapes they examine a set of four identical figures pointing in various directions,...
Curated OER
Matching Directions
Which of these shapes is pointing the same way? Pre-readers examine five rows of familiar objects. The first item points to the right for each, and they must determine which of the subsequent items in each row points the same direction....
