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.

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...

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...

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...

Allow your students to review what they learned about animal characteristics with this PowerPoint. This slideshow includes 9 multiple choice questions and an answer key at the end. Tip: You can use this as an assessment by having your...

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,...

Tenth graders plot points on a coordinate plane. In this geometry lesson, 10th graders identify the different quadrants, plots points on a number line and coordinate plane and solve for the midpoint of line segments.

Eleventh graders explore quadratic equations.  In this Algebra II lesson, 11th graders use Geometer’s Sketchpad to explore the properties of quadratics and the connections with polynomials and linear equations.  The lesson is...
