Let's Take a Spin: One-Axis Rotation
Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...

Part and Whole
Now you'll never have trouble cutting a cake evenly again. Here is a set of five problems all about partitioning shapes into a given number of pieces and identifying the fractional amount of each piece. As learners progress through the...

Symmetry and Geometric Shapes on Campus
Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not.
Curated OER
Shapes from Shapes
Geometric shapes are really cool. Examine triangles, quadrilaterals, trapezoids, rhombuses, parallelograms, pentagons, and hexagons with your class. They draw large shapes and small shapes then compare them to understand their shapely...
Curated OER
Shapes in Motion
Students practice moving different shaped objects through a series of transformations. In groups, they discuss other ways to manipulate the figure to achieve the same results. They solve multiple story problems in the same manner.

Congruent / Similar Shape Cards
Cut apart 16 cards with 8 congruent pairs of geometric shapes, then have your class match the cards which show congruent shapes. There are no directions or information on the page so use your imagination to create a fun activity. Tip:...

I Spy Shapes
All your students have likely played the age-old game "I Spy," and now you can play it in the classroom! A leader (could be you to start) chooses something in the room with a familiar geometric shape. The class begins asking yes or no...

Pattern Recognition
In this pattern recognition worksheet, students determine which shape comes next in nine strips of shapes and then draw that shape on the line provided.

What Lies Behind “Same Shape”?
Develop a more precise definition of similar. The lesson begins with an informal definition of similar figures and develops the need to be more precise. The class learns about dilations and uses that knowledge to arrive at a mathematical...

Patterns, Relations, and Functions: Geometric Shapes
Students explore patterns involving objects or figures and geometric shapes. They identify the missing shapes in patterns and discuss what would come next in the pattern, analyze patterns using different objects, and complete a...
Curated OER
Geometric Abstraction
High schoolers create an abstract work of art that is made by repeating geometric shapes and lines, write concise instructions to reproduce the work of art and reproduce someone else's artwork via written instructions.

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...

Make Your Own Puzzle
Puzzling over what geometry activity to teach next? Look no further. This simple activity teaches young mathematicians how shapes can be decomposed into smaller figures, and how smaller figures can be assembled into larger shapes. To...

Shapes Around Us
Learners use manipulatives to study shapes. They sort shapes and use correct geometric terminology to describe them. Students find real-life examples of 2 and 3 dimensional shapes, and classify figures in their classroom according to...
Curated OER
Geometric Shapes and Figures
In this identifying shapes and geometric figures activity, students observe objects and choose the best answer to identify them. Students choose 6 answers.

Geometry 3D Shapes: Platonic Solids
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...
Annenberg Foundation
Geometry 3D Shapes: Surface Area and Volume
Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Figures Ahoy!
In this geometry instructional activity, students solve 4 problems in which a given geometric shape is recognized and circled in a group of shapes. Students cross out the shape in each set that is not like the others.
Curated OER
Geometry: Shapes and Pictures
In this geometric shapes worksheet, learners analyze 6 photographs of real life objects. Students write the name of the geometric shape or figure that fits each picture.
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.

Terrific Tangrams
Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.
Curated OER
Geometric City
Students brainstorm names of plane and solid geometric figures. Afterward, they explore the skyline of large cities and note their agricultural shapes. Using construction paper, students build 3-D geometric structures to create a skyline...
