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.

Students use a dictionary to gather appropriate information for writing simple definitions. They recognize prefixes that relate to numbers, such as mono-, bi-, and tri-. Pupils use their creative abilities to extrapolate new words to...

Eighth graders classify geometric figures.  In this polygon lesson, 8th graders identify given geometric figures.  They compare and contrast different polygons.  Students name line segments, identify parallel lines, and...

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.

Fifth graders explore polygons. In this math lesson plan, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Learners identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

Young mathematicians classify squares according to attributes. They sort squares according to specific attributes. Students explore squares in repeating patterns and order squares according to size. Engaging extension activities are...

Students identify interior and exterior angles of polygons. In this geometry lesson, students add interior and exterior angles of polygons. They use angle theorems to solve the problems.

Students identify and classify solid geometric figures. In this geometry lesson, students bring in objects that look like solid shapes and identify their attributes. Students identify the number of surfaces and faces on each figure.

Student sinvestigate the area and perimeter of polygons. They differentiate between similar and congruent polygons.. They identify the ratio and proportions of the sides and angles of polygons.

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...

Don't worry if you do not have the mentioned textbook; there is enough material here for you to carry out a pertinent polygon plan. After introducing your class to various polygons and the prefixes that help identify them, hand out...

Students analyze different polygons by shapes and sides. In this geometry lesson, students differentiate between similar and congruent polygons. They name the different polygons based on the number of sides.

High schoolers define and identify shapes by name. In this geometry activity, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.
