Junior Architects of America
Students create entries for the Architects of America contest, including a model of a futuristic structure, blueprints, a list of all plane and solid shapes in the structure, a persuasive argument paper that describes why the structure...
Curated OER
Marshmallow Figures
Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3 dimensional...

I've Seen That Shape Before
Students identify geometric solids. In this shape lesson plan, students explore the characteristics of geometric solids. They locate pictures of shapes on the internet, and identify the shapes. Students draw pictures of...
Curated OER
Polygons and Plane Figures
Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.
Curated OER
Geometric Solids
Fourth graders examine the properties of geometric solids. Given geometric figures, they brainstorm observations. In groups, 4th graders identify solids and discuss the physical properties. Each student creates a Venn diagram and...
Curated OER
Spaces and Places
Students identify three-dimensional forms in various buildings and construct three-dimensional paper forms.
Curated OER
Angle Exploration and Classification
Learners compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.
Curated OER
3-D Cubes
Students investigate cubes. In this geometric solids activity, students review geometric concepts previously taught, then logon to a computer game in which they find cube figures and identify the shadow of hidden cubes.
Curated OER
Spacemobiles
Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...
Curated OER
Shape Up!
Learners investigate measurement through the use of literature through this series of lessons.
Curated OER
Polygons
Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.
Curated OER
3-D Figures Part 1
Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory...
Curated OER
Sort it Out
Students identify and sort a variety of two- and three-dimensional objects and compare and contrast their attributes. They identify shapes, locate shapes on the faces of solids, sort real objects and explain the sorting rule, and...
Curated OER
Cube Net
In this math worksheet, students cut, fold and tape the math net to construct a model of a cube. Students learn to recognize the solid geometric shape of the cube.
Curated OER
Geometry and Shapes
Fourth graders are asked to name different shapes.Four to five students to share their answers with the class. The teacher leads the discussion in geometry about the properties associated with shapes.
Curated OER
Copy Cat
Young scholars examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
Curated OER
Where has Polly Gone?
Students explore polygons and their uses in careers. They also discover polygons shapes in manmade objects and nature. They use their acquired knowledge to construct a strong structure using polygon shapes.
Curated OER
How many edges do I need to cut in order to open a cube?
Students problem solve to open a cube to create different shapes. In this problem solving lesson plan, students are given a cube and the shapes to open it up to, and they have to cut the cube open to make certain shapes. This gives them...
Curated OER
Marshmallow Geometry
In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.
