Second graders describe a polygon in the form of a riddle.

Students examine the idea of "regularity" as it pertains to geometry.  In this geometry lesson students complete several assignments that are part of trihedral angles and regular polyhedrons.

Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

Pupils classify polygons by name and shape. In this geometry instructional activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

Young scholars investigate the usage of parallel and perpendicular shapes in the real world. In this geometry lesson, students investigate shapes for properties that are related to the real world. They relate all the properties of shape...

Students recognize and identify shapes in their environment. They investigate why objects can be composed of several different shapes. They follow a pattern to recreate designs using various shapes.

Learners calculate the surface area of different prisms. For this geometry lesson, students identify the shapes of solids based on the properties of that solid. They calculate the surface area using nets and properties of prisms.

Students define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Students are introduced to the topic of area. In groups, they share various techniques to help them identify different shapes and work together to calculate the area. They use this same knowledge to determine the area of animal tracks...

Pupils analyze Greek vase painting and create their own vase art. In this vase painting lesson, students analyze the design element shape and the relationship between figure and ground. Pupils design a figure/ground relationship using a...

Students create a creature using Amaco cloud clay. For this sculpting lesson, students use clay, toothpicks, and clay modeling tools to create a unique clay creature. Students shape the clay into a four-legged animal.

Young scholars create a holiday ornament. In this Keith Haring art lesson, students use paper mache to make 3-dimensional ornaments that resemble his work. Young scholars cut out felt shapes of babies, dogs and angels then sew them...

Eighth graders describe the relationship between the visual aspects of "Easter Wings" and the poem's subject, and theorize about the poet George Herbert's motivations in constructing the poem this way. They demonstrate their ability to...

Students define trapezoids and their shapes. For this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

Second graders explore triangles and quadrilaterals. They rotate to various centers in the room to identify and examine triangles and quadrilaterals. After presenting a picture to the class, 2nd graders locate right angles, triangles...

Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...

Students differentiate between inscribed quadrilaterals and parallelograms. In this geometry lesson, students identify the shaped of the polygons when it is inscribed inside of a circle. They calculate the missing angles of the inscribed...

High schoolers design a cafeteria floor plan. In this area and perimeter lesson, groups create an efficient lunchroom layout on poster board by using geometric shapes and formulas as the basis for their designs. In the accompanying...

Students explore the concepts of length, perimeter and area. Students develop an understanding of length, perimeter, and area. Students calculate the area and perimeter of random shapes and calculate the area and perimeter of a triangle...

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Students infer the galaxy shape.  In this structure of the galaxy activity students observe the distribution of objects in the sky and answer questions.

In this spatial relations worksheet, students identify the number of triangles in a given figure, identify the number of cubes that a plane intersects, and determine the number of line segments in a given cube. This three-page worksheet...

Learners use shapes and manipulatives to demonstrate patterns. In this patterns lesson plan, students also break up patterns to identify a pattern unit.
