Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

Students identify the properties of a dragon curve. For this geometry lesson, students identify sequences and patterns as they solve fractals. They investigate patterns found in nature.

Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

Students observe how certain geometric shapes can be used to make some structures rigid and others flexible. The activity involves construction of a 30-60 right triangle, folding while following directions, and identifying polygons.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Students explore characteristics of shapes by making and using tangram sets. They discover how the tangram pieces are related to one another, and determine how many different combinations of the triangles, squares, and parallelograms in...

Students view a video to discover how patterns in nature relate to math. They explore the concept of exponential growth by observing and creating fractals. They solve and design word problems.

Students explore finding the surface area and volume of cubes and cylinders. They construct similar three-dimensional figures from a two-dimensional drawing. Students derive the formula for volume and surface area through examination...

Pupils use FoilSim to complete the activity and investigate the factors that affect lift and how wing area and lift are related.

In this math worksheet, students build a truncated dodecahedron. This is a solid shape with 12 regular decagonal faces and 20 equilateral triangular faces. Students build this shape to assist in developing their cognitive and geometric...

In this math worksheet, students use a paper model to build a truncated icosidodecahedron. The worksheet includes a model that is to be cut out and put together by the student. There is an option to include a small preview of the...

In this math worksheet, students build a model of a truncated icosahedron. This shape has 12 regular pentagonal faces and 20 regular hexagonal faces. An option to include a preview of the finished model is included for the teacher.

In this dodecahedron worksheet, students build a model of a dodecahedron. The pattern for this shape is made up of twelve pentagons. This is a worksheet generator, and the teacher can choose if a sample of the completed shape will be...

For this math worksheet, students use the math net pattern to construct a model of a rectangular prism. Students cut, fold and tape this 3 dimensional figure.

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Fifth graders classify triangles. For this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Study geometry through the concept of quilt design. High schoolers examine the geometric shapes in various quilts and then create their own quilts using geometric shapes that fit together. In the end, they write a paragraph to...

High schoolers explore the concept of fractals. In this fractals activity, students discuss Sierpinski's Triangle using an applet. High schoolers discuss the patterns involved with fractals. Students discuss the area of Sierpinski's...

Students explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. Students place dots on the screen to recognize that they have created Sierpinski's Triangle.

Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...

Second graders create a Geo-Folder based on geometric terms and concepts. They make a Table of Contents that guides them through the process of assembling a folder of completed activities.

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
