Students explore polygons and their uses in careers. They also discover polygons shapes in manmade objects and nature. They use their acquired knowledge to construct a strong structure using polygon shapes.

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Fifth graders identify lines of symmetry., similar and congruent shapes. They use construction paper to create their own symmetrical shapes. Students create stained glass frames containing symmetrical, congruent and similar shapes.

Students identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have been...

Third graders engage in a instructional activity that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while...

Learners will differentiate between inscribed and central angles in this geometry lesson. They answer questions dealing with circles as they relate to inscribed triangles and angles. This assignment includes a printable worksheet.

Third graders construct tangrams. In this tangrams instructional activity, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.

Students explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their partner...

In this minerals worksheet, students read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

Students differentiate between metallic and non-metallic sounds. In this music instructional activity, students listen to the audio clip of "March" and march in time with the music. Students identify the metallic sounds in the music...

Sixth graders build figures out of tangrams. In this symmetry lesson, 6th graders view tangrams and identify the polygons included in them. Students divide into groups, identify their tangram pieces, define the lines of symmetry, and use...

Students discover the sum of the interior and exterior angles of several polygons. In this Geometers sketchpad lesson, students work in groups to find the stated measurements of triangles, quadrilaterals, pentagons and hexagons. Students...

Students research endangered animals. In this animal science lesson, students visit suggested websites to learn more about endangered animals and create animal masks. Students need glue, cardstock, string and feathers to construct the...

Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

Students investigate the physics of flight through various experiments. In this physics lesson, students construct different flying objects. They explain the dynamics that make these object fly.

Fifth graders examine the geometry of quilts. They discuss the history of quilting, design two nine-patch squares, exchange one design on an Internet bulletin board, and construct a hot pad that is quilted.

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

What is black and white and re(a)d all over? Class members build a table out of rolled newspapers. Pupils follow the design process to design, build, and test their paper tables in the second challenge in a series of five.

Off they go — launching rockets is fun. The lesson plan contains templates to build paper rockets that can be launched from a PVC pipe launcher. Individuals or groups build the rockets and determine the shapes for their fins. Included...

Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

Learners construct frieze patterns using translations and rotations. They will discuss how frieze patterns are similar to jigsaw puzzles and use Cabri Jr. to build a triangle frieze pattern using rotations, translations, and reflections.

Students examine the food pyramid and construct a healthy meal. For this food pyramid lesson, students examine the new food pyramid that includes fats and oils, and is arranged with brightly colored triangles. They use grocery store adds...

Students measure angles using a protractor. In this geometry lesson, students solve for the missing angles using equations set to the theorem of triangles. They measure missing angles through construction and identify congruent angles.
