In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.

In this three- and two- dimensional geometry worksheet, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of each...

In this exploring projective geometry worksheet, young scholars use computer software for instruction, then answer 9 questions about 3D drawings.

In this isosceles right triangle learning exercise, 10th graders solve and complete 5 different constructions of composition and decomposition. First, they make 4 congruent isosceles triangles with the model on the left. Then, students...

Young scholars create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground...

Students explore two-dimensional and solid shapes. For 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...

In this polygon activity, students identify and create a six-pointed star by completing 6 steps. First, they use a compass to trace a circle with a given radius. Then, students draw a point on circumference of the circle and place the...

Students investigate architecture and construction by building a home from cardboard tubes.  In this housing lesson plan, students collaborate in groups to plan and create buildings they can fit in made from cardboard tubes,...

Fourth graders explore geometry by utilizing pattern blocks. In this pattern lesson, 4th graders analyze two separate pattern block shapes and discuss which one is bigger and smaller. Students collaborate in small groups to create...

Students explore geometry by creating jewelry in class. In this polygons instructional activity, students identify different shapes and characteristics while creating polygon figures from construction paper. Students utilize a...

In this geometry worksheet, students practice constructing a variety of graphs with various degrees of vertices. Students determine whether 12 graphs have an Euler circuit or path.

Third graders identify two and three dimensional shapes used in architectural designs by viewing images on the Internet.  In this geometry lesson, 3rd graders create their own building designs and identify the geometric shapes that...

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...
