Face the vertex of two-dimensional shapes and discover what each figure requires as part of its classification. With one shape per slide, learners see what makes each shape special and compare it to others with similar qualities. 

Students investigate the concepts related to observing two dimensional objects. They also build three dimensional objects using the two dimensional objects. The students give an oral or written explanation for how the pieces fit together...

Students compare and contrast world maps and globes. They convert a 3-dimensional globe to a 2-dimensional map. They are introduced to the Mercator map projection. They observe map distortions of shape, area, distance, directions and angle.

Fifth graders draw 2-D and 3-D shapes. They sketch and label geometric figures with correct terminology, then explore parallel and perpendicular lines. Pupils sort and classify shapes drawn.

Name that shape! This simple worksheet has learners identify each geometric figure. They examine rectangular prisms, cylinders, rectangular pyramids, and hexagonal prisms. This one-page worksheet contains 8 problems, and the goals seems...

Young scholars explore the concepts of length, perimeter, and area. In this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

Students problem solve to open a cube to create different shapes. For 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...

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...

In this shape lesson, learners cut out tangram shapes and create different pictures with them. They look at 3-D shapes as well. There is a nice, hands-on component built into this lesson.

Students explore differents types of triangles and quadriaterals. In this polygon lesson plan, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate lesson would be an excellent choice for...

Students study about our dependence on the earth's resources for materials. They practice their knowledge of geometric shapes by recognizing them in the context of the story.

How different can 3-D and 2-D really be? An engineering resource provides an explanation about the importance of two-dimensional technical drawings. Several samples show how to create multi-view drawings from pictorials and...

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

If you could build your own treehouse, what would it look like? Using a piece of contemporary art as inspiration, learners draw their own treehouses and add geometric and organic shapes. The lesson plan touches on Visual Thinking...

Take a similar approach to three dimensions. Pupils develop the relationship between areas of similar objects and see how they relate to the ratio of the sides. Building upon area formulas, small groups put together volume formulas for...

Students complete activities to learn about the shapes and their vertices. In this shape recognition lesson plan, students discover the rule linking the number of sides with the number of vertices for shapes. Students categorize...

Second graders identify different polygons and their attributes. In this geometry instructional activity, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and...

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

Students collect natural objects and draw these objects with and without shading.

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

Third graders compare and contrast the attributes of two-dimensional shapes. Using a tetrominoes game, they create two-dimensional shapes to cover up a game board. At the conclusion of the game, 3rd graders discuss the patterns they...

Students observe two-dimensional shapes and work on the challenge that what is observed is as important as what is not observed. Students determine constructions, rules and connections. Full references listed for further reading and...

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...
