Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...

Elementary school learners investigate the attributes of a square. They discover that squares are polygons and examine squares found in everyday life. They concentrate on connecting the word, square, with the shape. As an...

Which ones are square corners? As they learn more about shape attributes, be sure scholars understand the difference between a vertex and a square corner. After examining two examples, learners circle the 90-degree corners in 12...

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Investigate polygons from rectangles to triangles to octagons. Each level of the five-problem series targets a different grade level. Beginning with the level A problem, learners examine the relationship between area and perimeter by...

Students identify and classify solid geometric figures. In this geometry instructional activity, students bring in objects that look like solid shapes and identify their attributes. Students identify the number of surfaces and faces on...

Students investigate circles and spheres. In this space shapes lesson, students compare and contrast two-dimensional and three-dimensional shapes. Students investigate the relationship between plane and space shapes.

Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

Shape shifters examine and experiment with pattern shapes.  In this geometry lesson, they work in groups to name and describe pattern block shapes, and they discover the combinations of shapes that can be placed inside a hexagon.

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

Students problem solve to open a cube to create different shapes. In this problem solving lesson plan, students are given a cube and the shapes to open it up to, and they have to cut the cube open to make certain shapes. This gives them...

Students explore expression in artwork. In this interdisciplinary lesson, students travel to ancient Egypt to examine abstract art of the Nile River valley through several hands-on activities.

Students describe shapes to other students who have to guess that shape. In this shape lesson plan, students describe shape attributes to other students. Then those other students have to guess the shape that is being described to them....

Second graders explore and analyze plane shapes. In this plane shapes lesson, 2nd graders evaluate shape attributes to classify shapes correctly. Students work in groups to create different shapes.

Third graders create 2D and 3D shapes using marshmallows and toothpicks. In this geometry lesson, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...

Third graders describe and compare attributes of two-dimensional shapes. They explain geometric terms, angles and shapes. Students demonstrate each vocabulary word with their body and they mirror the body positions associated with each...

Learners calculate the lines of symmetry using polygons. In this geometry lesson, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.

Young mathematicians classify squares according to attributes. They sort squares according to specific attributes. Students explore squares in repeating patterns and order squares according to size. Engaging extension activities are...

Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...

Students explore the concepts of length, perimeter, and area. In this math instructional activity, students use Shape Explorer to practice finding length, perimeter, and area.

Students are assigned to shape groups and explore three-dimensional shapes. They review math skills and two-dimensional shapes.

Third graders use various shapes to identify polygons and understand symmetry. They explore pattern blocks noticing their similarities and differences, then share with other team members. They draw 3 polygons in their journals and...

Fourth graders investigate regular polygons. In this regular polygon lesson, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
