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...

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

Expose youngsters to 3-D objects in a hands-on learning activity involving marshmallows and toothpicks. Engage your young mathematicians by introducing them to 3-D shapes by means of a story book. Explore 3-D shapes by manipulating...

Create three dimensional objects in an applied science activity. 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.

Students 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.

Shapes are really neat, and here's a lesson 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 shape...

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...

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...

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...

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...

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...

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...

Nurture a love of math and farming at the same time. Pupils apply geometry concepts, such as surface area and volume of three-dimensional shapes and similarity ratios, to farming contexts. They consider the dimensions of bales of hay,...

Students use the Pythagorean Theorem to solve problems. In this geometry lesson, students solve for the distances by calculating the different parts of the shape of a two and three dimensional shape. They reason by analogy.

Students are asked to visualize three-dimensional figures and apply this visualization to problem solving.

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...

Students sketch cones and identify its properties. In this geometry lesson, students calculate the surface area and volume of each three dimensional shape. they define and sketch prisms, pyramids and cylinders.

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...

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

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...

Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

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.
