Geometry Flip Book
Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...
Curated OER
A Sphere and Its Net
Students identify and sketch the nets for sphere. In this geometry lesson, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.
Curated OER
Folding to Make Shapes
Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...
Curated OER
Yummy Shapes
Pupils explore space shapes learning about edges, corners, and faces. They enjoy shape soup as a culminating activity.
Curated OER
Property Lists for Quadrilaterals
Students establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

Geo Jammin' - Day 2, Lesson 5: Eeny, Meeny, Miney, Mo
Students, in groups, use song lyrics and math to descrie two and three dimensional shapes.
Curated OER
Identifying Three Dimensional Figures (3)
In this 3 dimensional figures worksheet, students study the 10 3-dimensional figures. Students identify and label each of the 10 figures.
Curated OER
Exploration with Geometric Solids
Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.
Curated OER
Shapely Figures
Students are given magazines, scissors, glue, and one sheet of construction paper. They look for pictures showing real life representations of rectangular prisms, spheres, cones, and pyramids. Pupils cut out pictures showing each of...
Curated OER
Conics in Geometry
High schoolers analyze characteristics and properties of two and three-dimensional shapes in this geometry lesson. They follow detailed directions to use the Cabri Geometry II Application on their TI-89 calculator to construct a...
Curated OER
Identify Cones
Third graders evaluate the attributes of cones. In this space shapes instructional activity, 3rd graders analyze three-dimensional shapes. Students explore the faces and edges of a cone.
Curated OER
Opening A Cube
Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...
Curated OER
Geometry Institute Lesson
Students practice geometry skills. In this geometry lesson, students find the surface area of cubes and prisms, identify shapes on solids, and distinguish between 2-dimensional objects and solids.

Grandfather Tang's Story
Learners recognize, describe, and perform transformations (rotation/turn, reflection/flip, and translation/slide) on two dimensional shapes.
PBS
Surface Area and Volume
You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...
Curated OER
Searching for Angles and Lines
Young scholars work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.
Curated OER
Marshmallow Geometry
Third graders create 2D and 3D shapes using marshmallows and toothpicks. In this geometry lesson plan, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...
Curated OER
Tessellation Project
Fifth graders will be predicting and describing the results of sliding, flipping, and turning two-dimensional shapes. They will also understand patterns so they can describe, extend, and make generalizations about geometric and numeric...
Curated OER
Third Grade Geometry
Third graders describe 2D and 3D shapes. In this geometry lesson plan, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they...
Curated OER
Surface Area and Measuring
Tenth graders explore volume and surface area through percentages. In this geometry instructional activity, 10th graders analyze the surface area of two and three dimensional shapes, then use percents and ratio to compare the two.
Curated OER
Three-Dimensional Figures
Sixth graders explore three-dimensional objects. In groups, they create and decorate their own polyhedron design. After identifying the faces, vertices, and edges of the polyhedron, 6th graders determine a relationship between the...
