Symmetry is a term found in art, math, and science, prep your students to encounter symmetry from any angle. This presentation provides several simple examples of shapes that do and do not have a line of symmetry.

A very clever marriage of social studies and math is offered in this presentation. Young mathematicians look at slides of a variety of flags of the world and try to find the line of symmetry in each. A clever way to practice symmetry!

This presentation is intended to accompany an entire unit and covers a wide variety of concepts. Counting on, counting back, symmetry, properties of 2-D shapes, completing symmetrical patterns, and measuring angles are all covered.

Your Spanish students will see what symmetry looks like on a quadrilateral, triangle, and circle  in this presentation. Large, bright shapes are displayed with lines of symmetry, followed by examples that do not show a line of...

A strong PowerPoint provides several examples of lines of symmetry found in nature. Each slide shows a different picture and asks the question, "Where are the lines of symmetry?" This resource would be good for reinforcing the concept of...

In need of a fun way to define an isosceles triangle? This activity has learners fold a paper in half and then cut it to create an isosceles triangle. They determine the line of symmetry by folding the triangle in half and then use the...

The class thinks about symmetry and patterns. They view several symmetrical patterns represented as dots with a mirror in between. They discuss which images are symmetrical and which are not, then color in dots to complete a few...

Here's a lesson that just might make your class squirm! Learn about segmented worms in a detailed PowerPoint presentation including the wriggly earthworms young scientists dig up in their backyards. Although seemingly simple creatures,...
