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...

This collaborative activity investigates the meaning of a trapezoid and a parallelogram. It begins by presenting two different definitions of a trapezoid. Learners are to reason abstractly the difference between the two definitions and...

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...

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.

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...

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...

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.

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...

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...

Second graders explore and analyze plane shapes. In this plane shapes lesson, 2nd graders evaluate shape attributes to classify shapes correctly. Students work in groups to create different shapes.

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.

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...

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 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...

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 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 analyze the difference between shape and form. They identify, explain and use the basic elements of design and determine that forms are three-dimensional and shapes are two-dimensional. They sketch it on their paper and then...

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

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 comprehend how Landsat satellites orbit teh Earth to produce images. They comprehend the elliptical path of satellites. Students recognize that a different orbital path is needed for different satellites to perform their tasks....

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.

Students use cubes to construct and visualize two-and three-dimensional shapes to develop spatial thinking and review basic geometric principles through real-life applications. They are given the opportunity to build and build and take...
