Sixth graders find the perimeters of polygons and use perimeters to form polygons. In this perimeter lesson, 6th graders study vocabulary associated with finding perimeter such as polygon, line segment, variable, and formula. They make...

Tenth graders explore the properties of the incenter of a triangle. In this geometry lesson, 10th graders construct a triangle and the angle bisectors of each angle. The dynamic properties of Cabri Jr. allow students to locate and...

In this interactive activity, students review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations....

Young scholars investigate the properties of circles. For this geometry lesson, students calculate the area and perimeter of a triangle. They identify the perimeter and radius length of a circle.

Third graders incorporate math into dancing. In 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 plan, 4th graders create a symmetrical animal collage by cutting and gluing geometric shapes and figures from math...

This extensive and far-reaching collection of worksheets puts a new twist on many basic concepts. Learners use multiplication to trace a path from one point to another, tile a plane by converting between improper and proper fractions,...

Third graders engage in an enrichment lesson exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements. They then create a...

Students calculate the center mass of a triangle. In this geometry lesson plan, students use the median to find the center mass. They discuss the different characteristics of triangles and their center of mass.
