Math Mammoth: Polygons: Introduction

Third graders investigate congruent polygons through dance. For this congruency lesson, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Fourth graders practice finding the perimeter of shapes.  In this measurement lesson, 4th graders review the meaning of perimeter and work in groups to draw polygons with differing perimeters.  Students share their polygons...

Third graders incorporate math into dancing. For this algebra lesson, 3rd graders identify different shapes and patterns using dance movements. They relate the different creations to polygons as they incorporate the use of stretchy bands...

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

Fourth graders use dancing methodology in a polygon and shape activity. In this shape and dance instructional activity, 4th graders discuss shapes in dance, math, and everyday life. Students use dancing activities to recognize and...

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry lesson. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden...

Students work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the lesson. In part two, students use geoboards to construct polygons, look for patterns, and find a general rule.

Learners follow a series of instructions for drawing and coloring different shapes in order to learn the difference between the perimeter and area of a polygon. Then they are asked to find the perimeter and area of a 3x4 rectangular...

This video looks at the properties of circles and students are shown how to draw them using a compass, as well as how to draw one inside a square and how to copy a circle design. [9:23]

Not particularly coloful, but definitely informative, here is an introductory presentation on polygons. The basic shapes are covered, from triangles to decagons. Special polygons like the trapezoid and the rhombus are also covered. Not...
