Students are introduced to the concept of symmetry by examining different shapes and folding them into equal halves. They work in small groups focusing on finding the lines of symmetry of one specific shape. A symmetry booklet is made by...

Fifth graders use estimation to solve word problems. In this fractions lesson plan, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation. This...

Students define the terms polygon and perimeter to begin the lesson plan. 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 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.

For this geometry worksheet, students find the sum of angles, label angles, and more. Students complete 6 questions total on this worksheet.

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

In this geometry worksheet #13 worksheet, 10th graders work in groups to solve 6 geometry problems, involving measurement of angles.

Students examine new shape possibilities by combining two and four triangles using manipulatives.

This interactive web lesson teaches students about two-dimensional shape attributes.

Generate different "nets" for paper construction of common three-dimensional shapes: cube, cuboid, pyramid, cone, tetrahedron, cylinder, octahedron, rhombic prism, dodecahedron, pentagonal prism, and pentagonal prism.

[Free Registration/Login Required] This flipchart helps students to analyze and compare various two-dimensional shapes according to the vertices, sides and parallel lines. It features "containers" created in Version 3 (can be used with...

The 'Platonic solids' are three-dimensional shapes formed by putting together identical regular faces. Every corner and every edge is identical to every other corner and edge. There are five such 'solids': the tetrahedron, cube,...

Did you know that two-dimensional shapes are also called polygons? This lesson describes the various 2-D shapes and includes two interactive games to reinforce skills.
