If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

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...

Second graders determine how to name two-dimensional shapes by their properties. In this two-dimensional figure lesson, 2nd graders work in two groups. They work with the teacher to examine two-dimensional shapes and complete a...

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Students compare and contrast similar two and three dimensional shapes within cooperative groups.

You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...

Sixth graders use toothpicks and gumdrops to make prisms and pyramids. This helps them explore the relationship betweeen faces, vertices, and edges.

Third graders create 2D and 3D shapes using marshmallows and toothpicks. For 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...

Learners 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 create polygons requested by their teacher. In this polygons lesson, 5th graders watch a video and listen to a song about polygons. Then, students take turns labeling various polygons and practice making polygons.

In this math vocabulary worksheet, students complete multiple choice problems where they match the correct math vocabulary word to its definition. Students complete 15 questions.

In this second grade geometry learning exercise, 2nd graders answer 10 multiple choice questions about geometric shapes, with the answers available online.

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...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

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...

Through a series of activities, learners are exposed to how artists use symbolic imagery to create the narrative of a subject’s life. They study The Birth of Alexander and some manuscripts kept at J. Paul Getty Museum. They then draft...

Animals oftentimes elicit various characteristics which make them symbolic or representative of human feeling, action, or emotion. The class creates horse characters out of clay to show character action and symbolism. This is a great...

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...

Sixth graders create three-dimensional black and red figured Greek Vessels out of papier-mache, while researching and discussing Greek history, and myths of powerful gods and goddesses.

Middle schoolers explore dissecting planes. In this biology lesson plan, students learn the basic vocabulary used in dissection, learn how to orient themselves on a three dimensional figure, and develop the manual dexterity necessary to...

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 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 create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

So a cylinder does not have to look like a can? By expanding upon the precise definition of a rectangular prism, the lesson plan develops the definition of a general cylinder. Scholars continue on to develop a graphical...
