Cones Teacher Resources

What is the relationship between a hemisphere, a cone, and a cylinder? Using Cavalieri's Principle, the class determines that the sum of the volume of a hemisphere and a cone with the same radius and height equals the volume of a...

Geometric volume calculations are brought into the real world in a quick set of application problems. Learners are asked to help a patient figure out how to drink a prescribed amount of water both at work and at home. This activity...

In this geometry worksheet, students cut out a net of a cone by following along the dotted lines as indicated by the scissors icon. They fold the figure to form a three-dimensional cone which they tape together. There are no directions...

An excellent way to reinforce math vocabulary in your classroom! Seventy-eight posters focus on number and number sense, computation and estimation, measurement, geometry, probability and statistics, and patterns, functions, and algebra.

Which item is shaped like a cone? Use this multiple-choice shape recognition worksheet to give students access to shapes in their everyday life. Four questions ask scholars to identify which of the pictured items is shaped like a sphere,...

Add a sense of excitement to your math class with this race across the country. Using their knowledge of all things circular, young mathematicians work in pairs answering a series of pi-related word problems as they hop from one city to...

This video answers the question, What is an ellipse? It gives a definition of an ellipse, shows the ellipses relation of a plane to a cone, and the names of different parts of the ellipse.

The sky is the limit when printing custom 3-D shape templates from this site. Not only can you pick your shape and pattern, there is an option to upload an image for the different sides of the geometric shape. Let your learners have fun...

Students investigate the volume of cones. In this geometry lesson, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.

Use this activity on cross-sections of three-dimensional shapes in your math class to work on algebra or geometry Common Core standards. The lesson includes a list of relevent terminology, and a step-by-step process to illustrate the...

Learners solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities include...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

Primary geometers create a picture using tangrams. In this geometry instructional activity, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their...

Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate activity would be an excellent choice for...

Students read The Greedy Triangle and discuss geometric solids. In this geometry lesson, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

Math scholars study conics and how they are used today. In this mathematical instructional activity, pupils construct and slice cones after viewing a demonstration. 

Investigate the properties of three-dimensional figures with this Arctic-themed math lesson. Beginning with a class discussion about different types of solid figures present in the classroom, young mathematicians are then given a...

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...

Students identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson, students  build a cube by matching colored square faces to a correct word. Students then...

First graders explore 2-dimensional and 3-dimensional shapes. In this geometry lesson, 1st graders examine the attributes of 2 -dimensional and 3-dimensional shapes. They also create the shapes as they build models. This lesson...

In this geometry learning exercise, 4th graders find 13 words in a word search puzzle. They find words such as convex, prism, cylindrical, and cone which are placed diagonally, vertically, or horizontally in the puzzle.

Young visual learners explore different cross sections of 3-dimensional objects. First, cross sections of cubes are explored by using an interactive flash activity. This is then extended by looking at cross sections of spheres,...

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

Connect literature (Jack the Builder) with mathematical concepts. In a series of computation, geometry and number sense activities, pupils count on to add, count back to subtract, build cylinders, cones, and rectangular prisms, and name...
