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...

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...

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...

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson plan. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber...

Create three dimensional objects in an applied science lesson. The goal is for your class to recognize, compare, and model shapes. Using cookie cutters and clay or play dough, they create models for three-dimensional shapes.

Young scholars participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

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...

Shapes are really neat, and here's a activity that will help learners identify shapes through song, touch, and sight. They sing a shape song as they bounce different shapes around in a parachute. They then read a story and feel each...

Students identify basic two-dimensional shapes. They are able to identify the four basic two-dimensional shapes: squares, rectangles, triangles, and circles. Students write/draw in their learning logs a reflection of what they noticed...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this instructional activity. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is...

Explore methods for finding the volume of different three-dimensional figures. The 20th lesson in the 25-part series asks learners to interpret diagrams of 3-D figures and use formulas to determine volume. Scholars must use the...

Students explore models of three-dimensional shapes. In this geometric shapes lesson, students use hands-on manipulatives to explore three-dimensional shapes. Students predict whether each shape will roll or slide.

Students explore characteristics of geometric shapes. They observe geometric shapes and forms in public sculpture. Students create a unique sculpture of their own using basic three dimensional shapes. Additional cross curriculum...

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.

Using geoboards, computer programs, and hands-on manipulative materials, elementary schoolers engage in a study of two and three-dimensional geometric shapes. This lesson is chock full of good teaching ideas on the subject, and the...

High schoolers identify the volume of cones and pyramids. In this geometry lesson, students derive the formula for cones and pyramids. They calculate the volume of cones and other three dimensional shapes.

Learnersinvestigate three-dimensional shapes. In this geometry lesson, pupils calculate the volume of cylinders using the given dimensions. They create a formula base don observation before using the real formula.

Second graders organize solids into categories, depending upon whether they will roll, slide or do both on a home made ramp. Students describe and compare attributes of three-dimensional geometric solids.

Second graders create a three-dimensional picture of a sheep after observing a variety of templates of sheep. They then verbally identify the texture and color of the sheep. Students also read a book about sheep such as, "Sheep in a...

Students study geometric shapes and practice naming them properly. In this geometry activity, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...

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...

Students investigate the volume of cones. In this geometry lesson plan, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.

Young scholars explore geometry by participating in a shape identification activity. In this figure dimensions lesson, students identify the difference between 2 and 3 dimensional shapes by their vertices and faces. Young scholars...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...
