Students observe solids and identify parts that make up the surface area. In this geometry lesson, students calculate the surface are of solids and cones. They find polygons and solids in the real world.

Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...

What does a squared and b squared make? C squared of course! The pre-test assesses eighth graders' knowledge of the Pythagorean Theorem, application of the Pythagorean Theorem, and finding volumes of solids. 

In a two-part worksheet, young geometers examine 3-D shapes and describe their attributes in a table. They will be able to draw the shape and name the number of vertices, faces, and edges. In the second part, individuals explore...

In this perimeter and area worksheet, students find the surface area of given polygons.  They determine the area of shaded regions.  This one-page worksheet contains 10 multiple-choice problems.  Answers are provided.

Students recognize the features of geometric shapes.  In this geometric shapes lesson, students listen to Captain Invincible and the Space Shapes. Students create solid figures with marshmallows and toothpicks.  Students create...

Third graders investigate shapes in our world. In this geometry instructional activity, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic...

Learners explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Fifth graders explore three-dimensional figures. As a class, they discuss the characteristics of various three-dimensional figures. In groups, 5th graders write riddles describing the geometric shape. Partners read each other's...

Middle schoolers identify objects that are the same shape and size. They compare and contrast attributes of two-and three-dimensional objects using appropriate vocabulary. Pupils justify an extension of a geometric pattern to explain...

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...

Don't let the task slip through your fingers like sand. Scholars design sand castles using hemispheres, pyramids, cones, and cylinders of different sizes. They calculate the volume and surface area and consider how changing the...

Finalize the plans before playing in the sand. Learners design sandcastles using geometric and composite figures. They create blueprints, including the scale, and three-dimensional models of their castles. Finally, scholars calculate the...

From the apple on your desk and the coffee cup in your hand, to the cabinets along the classroom wall, basic three-dimensional shapes are found everywhere in the world around us. Introduce young mathematicians to the these common figures...

Who knew running a greenhouse required so much math? Amaze future mathematicians and farmers with the amount of unit conversions, ratio and proportional reasoning, and geometric applications involved by having them complete the...

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 lesson.

Students explore space shapes learning about edges, corners, and faces. They enjoy shape soup as a culminating activity.

Explore the concept of building equations for perimeter and circumference. Learners use rulers to measure the perimeter of half a sheet of paper.  Then fold the sheet of paper numerous times, each time measuring perimeter. ...

Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

For this shapes worksheet, students draw different shapes including a cone, a cylinder, and a sphere. Students complete 6 shapes total.

Students identify and sketch the nets for sphere. In this geometry instructional activity, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

This lesson starts with geometers discussing how to find the volume of a cone and pyramid, using what they know about the volume of a cylinder or prism. Then, using the formulas, they calculate the volume of cones and...

In this solids worksheet, learners compute the volume of prisms, cylinders, pyramids, spheres and cones.  This seven-page worksheet contains approximately 68 problems.
