Polygon Sum Conjecture
Students calculate the sum of the angles of a polygon. For this geometry lesson, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.

Three-Dimensional Figures
Sixth graders explore three-dimensional objects. Using various objects found in the classroom, they identify faces, edges, and vertices of objects. Students create their own objects. They describe the polydron, telling the faces,...

Children's Museum of Houston - Pre/Post Classroom Activities - Nets
Students make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

3-D Figures Part 1
Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory...
Alabama Learning Exchange
Pennies, Pennies and More Pennies
Learners determine the number of pennies needed to fill a room. In this pennies lesson plan, students work in groups to determine the number of pennies needed to fill a room. They compute the probability of the head of a pin landing on...
Curated OER
Comparing Covalent and Ionic Substances
In this covalent and ionic substances activity, students use the internet to find information about the characteristics of covalent and ionic substance and explain what causes the differences in these types of substances.
Curated OER
Polydron Fun
Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Shaping Up with Nature at Black Bayou Lake
Students visit a local lake refuge and identify shapes they find in nature. They take pictures of the various shapes and use KidPix to draw shapes around the shapes in the pictures. They watch a slideshow of all the shapes found by their...
Curated OER
Where has Polly Gone?
Students explore polygons and their uses in careers. They also discover polygons shapes in manmade objects and nature. They use their acquired knowledge to construct a strong structure using polygon shapes.
Curated OER
Circles to Spheres
Young scholars investigate circles and spheres. For this space shapes lesson, students compare and contrast two-dimensional and three-dimensional shapes. Young scholars investigate the relationship between plane and space shapes.
Curated OER
That's So Square
Second graders are introduced to circles, triangles and parallelograms. As a class, they create the shape with their bodies and are shown the shapes in their actual size. To end the lesson, they sketch each shape and identify their...
Curated OER
Pythagorean Theorem
Students investigate the Pythagorean Theorem. In this seventh through twelfth grade geometery lesson, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right triangle.
Curated OER
Copy Cat
Pupils 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.
Curated OER
Pyramids & Prisms: Guler's Formula
Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the activity, they use the shapes they made and...
Curated OER
Euler Characteristic
Pupils identify the different properties of Euler's Characteristics. In this geometry lesson, students identify the shape and surface a polygon. They relate the concept of Euler to solving real world problems.

Geo Jammin' - Day 2, Lesson 5: Eeny, Meeny, Miney, Mo
Students, in groups, use song lyrics and math to descrie two and three dimensional shapes.
Curated OER
3-D Figures Part 2
Young scholars work with three dimensional objects. In this geometry instructional activity, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.
