Very simply, pairs of learners construct a model of the tetrahedral silica structure using raisins and toothpicks. They dip it into a soapy solution and then blow a bubble "atom" into its center. The lesson plan gives instructions that...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Middle-schoolers still enjoy playing with bubbles! For this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Learners sketch the shape of three dimensional pyramids using nets. In this geometry lesson plan, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.

Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the activity, they use the shapes they made and...

Students construct two dimensional models to illustrate squared numbers. In this geometry activity, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between various...

In this 3-D shapes worksheet, students practice identifying 8 3-D shapes with their following precise names: cube, cuboid, square based pyramid, cone, cylinder, tetrahedron, octagonal prism and hexagonal prism.

In this 3-D objects and common solids worksheet, students cut out and count the number of faces on several different types of boxes and make a cuboid from straws or a card. Students fill out 4 different categories involving 5 different...

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...

This hands-on instructional activity takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable...

Let your learners pick and create a fun shape from this custom template. Shapes range from complex geometric figures to the more common cube and prism. Each page can be labeled with your personal directions. Additional printable listed...

Tenth graders investigate the history of geometry and its different shapes. In this geometry instructional activity, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the...

In this geometry lesson, 10th graders fold a dollar bill to make a tetrahedron. They analyze geometric shapes and apply it hands on.

In this 3D shapes learning exercise, students cut out the 3D shape on the page and fold on the lines to create the correct shape. The learning exercise states which shape should be build with the cut-out.

Seventh graders explore the characteristics of three-dimensional figures. They compare the nets of figures. Students describe the relationship between the nets draw and the solid. They identify the vertices, edges and faces of the...

In this geometry worksheet, 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.

This page brings you to a table of contents of three-dimensional figures. Selecting a figure will bring you to a page defining and illustrating the figure with applicable formulas listed.

View and learn about five different polyhedra: tetrahedron, octahedron, icosahedron, hexahedron, and dodecahedron. Learn what Euler's Polyhedra Theorem is, and see examples of non-polyhedra as well.

At this one page website a variety of polyhedra are shown. The challenge is to create the skeleton for each polyhedron and identify the needed materials. You can check your solution right at the website.

Generate different "nets" for paper construction of common three-dimensional shapes: cube, cuboid, pyramid, cone, tetrahedron, cylinder, octahedron, rhombic prism, dodecahedron, pentagonal prism, and pentagonal prism.
