Classifying Polygons Teacher Resources

A straight edge, a right angle, a number of vertices; sounds like it's time to classify polygons. That's right you and your class will learn all about the properties of polygons and how to classify them with this easy to follow...

For your eyes only: classify the names of polygons. After providing the definition of a polygon, the video introduces the two major classifications of polygons, concave and convex. The segment of a larger playlist on geometry continues...

In this polygons worksheet, students write the name of the polygon, and if it is not a polygon they write "none". Students complete 9 problems.

Seventh graders participate in a polygon hunt.  In this polygon lesson plan, 7th graders examine how polygons are alike and different.  Students create a Venn diagram and label the sorting circles.  Students work in...

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...

Students study polygons. In this math lesson, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Students build as many different 2-dimensional polygons as possible: triangle, square, rectangle, pentagon,...

If it has three sides it's a triangle! Learn about the different types of polygons and how they are classified by the number of sides they have. This clip clearly defines each type of polygon, but fails to show examples.

A one-pager featuring 2-D quadrilaterals.

In this geometry activity, students classify polygons based on their sides and shape. There are 16 shapes to be identified with an answer key.

Seventh graders use block letter writing to help classify polygons. They use their own names which helps to keep them engaged during the lesson. Finally, 7th graders play a classification game naming different polygons.

Sixth graders explore different polygons. In this polygon lesson, 6th graders examine a rhombus, quadrilateral, parallelogram, and rectangles. Students compare and contrast polygons and research shapes on the Internet.

Eighth graders engage in a lesson that is about classifying polygons with the focus being upon specific triangles and quadrilaterals. They conduct activities using cutouts for kinesthetic learners to help make connections while...

Students classify polygons by name and shape. In this geometry lesson, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

For this line and angles worksheet, students explore basic geometry vocabulary.  They classify polygons.  Students determine the area and perimeter of given shapes.  They examine the parts of a circle, find volume and...

Elementary graders discover the concept of fractional pieces of a whole. They investigate the meanings of fractions in everyday life and why they are used. Pupils divide brownies amongst each other to demonstrate the use of fractions...

Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...

Learners classify triangles and make connections regarding angle measurements and attributes of acute, right, and obtuse triangles. They listen to teacher define and explain triangles. Everyone imagines a place where a broken wing for a...

Fifth graders work with polygons.

Seventh graders participate in a lesson that is focused upon the concepts of classifying different angles and triangles. They practice classifying triangles according to its kind that includes types of angles, congruence, and vertices....

Fourth graders explore obtuse triangles. In this geometry lesson, 4th graders make obtuse triangles with paper and scissors. They determine how to find the center of their triangle.

Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...

Fifth graders review EOG math terms and definitions found in their math notebooks, and pick between 15 and 20 words to put in a word search.
