Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.

Students classify prisms according to their attributes. For this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

Students identify the parts of three dimensional objects. In this geometry instructional activity, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

In this plane figure worksheet, students complete 4 multiple choice questions, determining which solid figure can be traced to make a given plane figure. A reference web site is given for additional activities.

Students review types of polygons and list several examples of each. They assume the role of a landscape artist interviewing for a job. They create sketches of their plans for six polygonal gardens and write an expository paragraph...

Fourth graders create mandalas. In this mandala lesson, 4th graders look at these polygons in nature and man-made forms. They create their own by using tangrams.

Students define the terms polygon and perimeter to begin the lesson. Using a calculator, they practice determining the perimeter of various symbols in a painting. They discuss how geometry and art are related to one another.

Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Students engage in a lesson plan that is concerned with the concept of quadrilaterals and how they are used to create a rectangle for a door. They create a drawing of a quadrilateral while finding the sum of the angles. They practice...

Students find the area of polygons.  In this area of polygons lesson, students find the area of parallelograms, rectangles, squares, and other polygons.  They identify each given figure and determine the appropriate formula...

Fifth graders work with polygons.

In this properties of angles worksheet, 10th graders solve and complete 3 different types of problems. First, they calculate the value of the missing angles in each diagram and explain the reasons for their answer. Then, students...

Fifth graders create math word problems. In this geometry lesson, 5th graders define perimeter and discover how to find the perimeter of a rectangle, a square and a regular polygon. Students write word problems on finding the...

Students explore Fractal designs. In this geometry lesson, students observe the different polygons created in nature and relate it to math. They define polygons on planes and rotate polygons about a point.

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

In this area instructional activity, 6th graders take a pre-test about what they may already know pertaining to geometric area.   Students respond to 10 multiple choice questions.

Learners explore tangram vocabulary and tangram designs, creating an art design that contains various geometric parts. They complete a checklist titled, Important Thing About a Quilt Design.

Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.

Learners predict the shape of molecules using VSEPR theory. In this chemistry lesson plan, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

Students view examples of man-made structures and create a building that matches the style. Using the internet, they research the style of Frank Lloyd Wright and create plans for creating their own community. They use a painting of...

Ninth graders access a star worksheet and determine properties of polygons.  In this investigative lesson students complete a worksheet and discuss myths. 

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Second graders describe a polygon in the form of a riddle.
