Students follow directions to make a stained glass window design of regular and irregular polygons with specific geometric elements. In this geometry lesson plan, students also analyze other classmate's designs.

Students complete worksheets where they calculate the perimeter of polygons. In this perimeter of polygons lesson plan, students divide complex shapes into simple shapes to find the perimeter.

In this polygons instructional activity, students fill out a graphic organizer about the name of the polygon, the number of sides, the angle sums, and more. Students complete this for 5 polygons.

In this polygons worksheet, students put a polygon jigsaw puzzle back together to form the planet Earth. Students put 10 polygons together.

Students discuss figures with various numbers of sides.  For this geometry lesson, students are read The Greedy Triangle by Marilyn Burns, they participate in a class discussion of many sided figures and are introduced to the term...

In this 2D shapes worksheet, students find the rectangular prism, triangular prism, pentagon, and triangle. Students have 3 shapes to choose from in each of the 4 problems.

In this triangle worksheet, 6th graders draw and cut out a triangle, cut it into three pieces, then arrange the pieces to make new shapes.

For this polygon worksheet, students find the sum of the interior angles of a polygon. They determine the perimeter of equilateral figures, identify concave and convex figures and explore the characteristics of equilateral, equiangular...

In this classifying shapes using Venn diagrams worksheet, students draw examples of isosceles, right, and equilateral triangles in the proper sections of the first graphic organizer. They draw polygons, both regular and quadrilaterals,...

In this tangrams instructional activity, 10th graders solve 7 different problems related to designing tangrams. First, they trace each of the figures shown on the sheet. Then, students cut out the pieces and rearrange them to form each...

Sixth graders identify, compare and interpret the characteristics of polygons and angles in order to meet spatial sense, geometry and measurement standards. They also sort shapes into three categories, polygons (regular and irregular)...

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....

Eighth graders solve problems using proportions with scaled drawings. They work with maps and blue-prints discussing scales and plans and examine different polygons and figure out the scale factors or proportions they have been changed by.

Seventh graders explore lines of symmetry, congruent polygons and patterns. They listen to "The Seasons Sewn," observe a PowerPoint presentation, and identify congruent polygons and visual patterns. Through an internet activity, 7th...

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

Students brainstorm different kinds of shapes. They then draw them on the paper and write the name of the shape on the back and then assemble the shapes to make a "monster". Students make up a survey about the monster including its name...

Learners begin the instructional activity by identifying what a polygon is and hypothesizing how many struts (diagonals) it would take to make a polygon rigid. They watch a "Magic School Bus" episode then experiment with various shapes...

Young scholars are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

Fourth graders compare and contrast gliding flight and true flight. They investigate the basic principles of aeronautics. The class participates in activities to observe lift and the effect of air. Students design and fly their own...

Students examine tesselllations and their geometric properties. They have a better knowledge of polygons, can identify types of symmetry in tessellations. Also students use visulization, spatial reasoning, and geometric modeling to...

Students participate in a game with different types of polygons. They use triangles to create as many polygons as possible. They also review their colors by having different polygons be a different color.

Twelfth graders apply perimeter measurement to items found in newspapers and calculate the cost in terms of feet or yards. They share answers and explanations with classmates.

Students recognize and name two-dimensional and three-dimensional geometric figures. One group of students will extend the study of polygons to quadrilaterals while another group of students will extend the study of polygons to...

Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.
