Some shapes have square corners, and some do not. Scholars participate in a sorting activity as they determine if these 12 shapes have square corners, categorizing them based on this attribute. Encourage geometers to draw the square into...

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. 

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...

Students construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Students use K'NEX materials sets to...

Students identify and match pictures of three dimensional shapes while playing a board game with peers. They take turns with their partners in spinning the spinner and moving to the next space on the game board that shows the same shape.

Third graders explore the attributes of 3-dimensional shapes. In this shapes lesson, 3rd graders examine faces, edges, and vertices of 3-dimensional shapes as they construct shapes using marshmallows and toothpicks.

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

In this math vocabulary worksheet, students complete 15 multiple choice problems, choosing the correct definition for a set of math terms. A reference web site is included for additional activities. 

Students use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Students differentiate between parallel and perpendicular lines. In this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Students explore sculpture. In this lesson plan about finding sculpture ideas in movement and rhythm, students make 3-dimensional shapes. Students create a sculpture paying attention to balance, rhythm and repetition. Students will...

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

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...

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

For this area worksheet, learners complete a ten question multiple choice test by finding the area of various geometric figures. This is an interactive worksheet.

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.

Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...

High schoolers identify various geometric shapes. Apply the given formulas to determine the volume of these shapes. Design their own container to conform to specifications provided. Use their knowledge of volume formulas and shapes to...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a instructional activity in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what...

Students explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their partner...

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...

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...

Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...
