From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

High schoolers discuss and identify polygons and lines. In this geometry lesson, learners review liner, square and cubic units so they can incorporate it into the lesson on measurement and creating packing that are cost effective.

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Students calculate the area of solids. In this geometry lesson, students use formulas to find the surface are and the volume of solids. They investigate 3-dimensional shapes.

Connect functions to geometry. In the ninth installment of a 12-part module, young mathematicians create functions by investigating situations in geometry. They look at both area and volume of figures to complete a well-rounded lesson.

Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

Take a swing at the task. Using their knowledge of polygons and solids, scholars design one hole of a miniature golf course. They calculate areas and perimeters, determine the cost of building the holes, make scale drawings, and create...

Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

Students investigate solids. For this geometry lesson, students use toothpicks and gum drops to solve problems. They create visuals to help them see what is happening to the shapes.

Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

Students define a plane and a solid shape. In this geometry lesson, students compare and contrast different geometric shapes as they relate to solids. They name the geometric solids based on their sides and edges.

Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...

Students explore points, lines and planes as it relates to geometry. In this geometry lesson, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Explore the volume of solids with a real-life connection. Learners calculate the volume of a deep-dish slice of pizza to determine its price. They model the slice as a part of a cylinder and create a formula for calculating the cost.

Third graders investigate shapes in our world. In this geometry lesson, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic organizers and conduct...

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

Learners explore geometry by completing a math worksheet in class. In this shape identification lesson, students identify the characteristics associated with 15 solid geometric shapes. Learners identify patterns between vertices, edges...

Young scholars discuss the importance of examining crystals and experiment growing them. In groups, they complete a project in which they use groups in geometry just like crystallographers. They practice solving the groups and proofs...

Students prepare to take the GED by reviewing basic math concepts. In this geometry instructional activity, students review vocabularies such as formula, perimeter, circumference and other important geometric terms. They convert between...

Students explore two-dimensional and solid shapes. For 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...

Students construct two dimensional models to illustrate squared numbers. In this geometry lesson, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between various figures...
