Fourth graders use polygons to create animal figures with symmetry. For this polygons and symmetry lesson, 4th graders create a symmetrical animal collage by cutting and gluing geometric shapes and figures from math activities.  

An excellent lesson on calculating the perimeter of a polygon, using real world tasks, awaits your students. They watch and discuss a PowerPoint presentation, identify objects in the classroom or on the school grounds that might create a...

At the end of the activity your learners will be able to classify a polygon by the number of ordered pairs given in a coordinate plane used as the vertices. this is the first video in a progressive series of four using geometry to solve...

Perimeter moves beyond squares and rectangles in a lesson on irregular-shaped polygons. The lesson focuses on the strategy of counting and then adding side lengths. Several examples are slowly walked through, giving learners plenty of...

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...

Take a multi-sided figure, such as a pentagon, and break it into smaller shapes to calculate the area. The video demonstrates this idea visually by breaking figures into small pieces and calculating each area. Also included, is a review...

Geometers hit the town to examine signs and analyze their geometric shape attributes. First, review these concepts using the linked podcast and assess comprehension with the interactive shape attribute tool, also an online link. As you...

The SmartBoard is utilized in this geometry lesson which has young mathematicians draw, identify, and define polygons. They access links embedded in the plan to gain practice in working with polygons, then take a quiz which is included...

Eighth graders plot points and investigate polygons. They locate a point, using ordered pairs of integers on the coordinate plane. Students compare geometric measurements and computations on coordinate axes as they are applied to...
