Students investigate polygons and construct ferris wheels. In this geometry lesson plan, students create a circle and differentiate properties of circles and polygons. They compare the relationship between angles and circumscribed polygons.

Students solve problems using the unit circle. In this precalculus lesson, students identify angles using the properties of the unit circle. They observe the trigonometric graphs and sine, cosine and tangent.

Students are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Sixth graders explore geometry by utilizing mathematical formulas. In this circumference lesson plan, 6th graders identify the difference between diameter, circumference and radius in a circle. Students review the formulas for finding...

Students investigate the Pythagorean Theorem.  In this seventh through twelfth grade geometery instructional activity, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side...

Students explore the difference between drawing and constructing a triangle utilizing The Geometer's Sketchpad on the computer. They create, develop and script constructions for both isosceles and equilateral triangles. Each student has...

In this geometry worksheet, young mathematicians divide a parallelogram into four, by choosing points along a diagonal.  Students calculate the area of each parallelogram and look for any patterns that may emerge.  The one-page...

Fifth graders, after seeing Honeycomb examples, complete a Classifying Angles worksheet, Clock worksheet, and Defining Angles worksheet.

Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...

Young scholars explore the concept of fractals. In this fractal lesson plan, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Young scholars develop these concepts through exploration and...

Sixth graders use yarn, paper plate, and other materials to identify parts of a circle. In this parts of a circle lesson plan, 6th graders identify the circumference, radius, diameter, and other parts of a circle.

In this polygon learning exercise, 5th graders name 6 polygons, tell if each one is a regular polygon or not and tell if it is a special quadrilateral.

In this geometry worksheet, students match terms with definitions, and complete short answer questions about polygons and congruency.

Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.

In this geometry worksheet, students read given sentences and identify the hypothesis and the conclusion of the conditional statements. There are 21 questions.

Students classify angles. In this angles lesson, students explore the characteristics of angles, triangles, quadrilaterals and circles. They identify polygons and sing a classifying angles song. Students participate in a manipulative...

Students become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there is...

In this geologic history worksheet, students answer questions about the earth's history, about dating fossils, about layers of rocks and about unconformity.

Pupils investigate similar triangles and proportions as they make conjectures about the length of sides of similar triangles. For this lesson plan, have your class construct similar triangles using Cabri Jr so that they share a common...

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

Eighth graders explore the characteristics of a circle and the formulas to find circumference. They use a bicycle wheel to determine the circumference around a wheel. They utilize a worksheet imbedded in this plan which has a variety of...

Students examine various "spaces" (including ones that are one-dimensional, two-dimensional, and three-dimensional). For each space, they will examine what it means to have or not have an edge, or to be finite or infinite.
