Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....

Fifth graders use formulas for calculating areas of squares and rectangles to find area of complex figure, compare their own ideas with their classmates' ideas, and recognize that there are multiple methods for finding area of complex...

Examine three Cubism art pieces by Pablo Picasso and Georges Braque with your students. They will research how Cubism was advanced due to Picasso and Braque. and then compare and contrast Cubist works through image based discussion. Your...

Pupils identify two and three dimensional shapes and use appropriate geometric vocabulary to write a description of the figure by taking pictures of geometric figures in their own environment.

Students are given magazines, scissors, glue, and one sheet of construction paper. They look for pictures showing real life representations of rectangular prisms, spheres, cones, and pyramids. Pupils cut out pictures showing each of...

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.

Students identify the ratios of different triangles. In this geometry lesson, students identify the similarity and differences of triangles. They use the navigator to move the sides of the triangle around.

Students sketch the nets for given polygons and cylinders. In this geometry lesson, students find the measurements that correspond with prisms, cones and cylinders. they identify parts of three-dimensional shapes.

Students sketch the shape of three dimensional pyramids using nets. In this geometry instructional activity, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.

Students define properties of rectangular prisms. In this geometry lesson, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Students explore the properties of rectangular prisms. In this geometry lesson plan, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.

Students sketch and identify properties of pyramids. In this geometry lesson, students create nets to identify three dimensional shapes. They sketch cones, prisms and pyramids.

Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.

Students create nets of cylinders. In this geometry lesson, students calculate the surface area of cylinders and other solids. They show their understanding of three-dimensional shapes by solving problems.

High schoolers sketch and create nets of different polygons.In this geometry lesson, students differentiate prisms from other three-dimensional shapes. They define the properties of prisms.

Seventh graders explore surface area. They study the difference between two and three-dimensional objects. The teacher leads a discussion about finding the surface area of different size cubes. In pairs, 7th graders use graph paper to...

Students identify geometric solids.  In this shape lesson, students explore the characteristics of geometric solids.  They locate pictures of shapes on the internet, and identify the shapes.  Students draw pictures of...

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Students research an area with at least one dominant geographical feature. Then they display their findings in a realistic 3-dimensional presentation. Students also prepare ancillary material to support their project. Finally, they chart...

Students describe, identify and compare two-dimensional figures. They also name and demonstrate the relative position of objects using directional words. They sort and compare two-dimensional figures and three-dimensional objects...

Learners explore the artwork of the Indo-Hispanic holiday of Day of the Dead. They view images, define key vocabulary terms, and plan and create a two- and three-dimensional sculptural figure.

Learners find the surface area of cones. In this geometry lesson, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the real world.

Students investigate spheres through sketches. In this geometry lesson plan, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.

Tenth graders investigate the volume of a cylinder.  In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The lesson progresses to the use of the formula to find...
