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...

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 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.

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...

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.

Shapes are really neat, and here's a instructional 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...

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

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...

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 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...

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...

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...

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

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...

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 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. Students examine blocks in...

Students study geometric shapes and practice naming them properly. In this geometry lesson, 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...

For 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.

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...

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

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.

Students compare and contrast world maps and globes. They convert a 3-dimensional globe to a 2-dimensional map. They are introduced to the Mercator map projection. They observe map distortions of shape, area, distance, directions and angle.

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...
