This story slide show will teach children about geometric shapes. As they listen to the story they will be exploring and visualizing solid geometric shapes while they enjoy the adventure with Sniffer Bob in the story. This story is as educational as ...it is entertaining. At the end of the slide show are instructions on how to make geometric shapes from paper. Aligned with K-2 National Geometry Standards.

This selection contains a detailed introduction to 3D objects and nets. Nets are 2D objects traced on paper,cut, and folded to make 3D figures. Key vocabulary defined include faces, edges, and vertices. The examples are shown on a computer screen ...accompanied by narration. (08:10)[more]

Learn about the attributes of solid shapes such as curves, ability to roll, slides, flat surfaces and corners. Learn the names of the basic solid shapes- cylinder, sphere, cone, cube and rectangular prisms. Some vocabulary may be too advanced for st...udents and a word wall might be of value. As well, if the students have access to the objects they could demonstrate the lesson and better retain the data.[more]

Describe relationships between two-dimensional and three-dimensional objects (squares/cubes, circles/spheres, triangles/cones). Name concrete objects and pictures of three-dimensional solids (cones, spheres and cubes).

This student-created video provides directions for making a net for a rectangular prism and a square pyramid. Demonstration includes use of a ruler to make sides the correct lengths. (02:52)

Identify the net (two-dimensional representation) that corresponds to a rectangular prism, cone, or cylinder. Recognize the three dimensional figure represented by a net. Make a net to represent a three-dimensional object. Make a three-dimensional mo...del from a net.[more]

Classify prisms, pyramids, cones, and cylinders by base shape and lateral surface shape. Classify three-dimensional figures by their attributes. Classify three-dimensional solids by their configuration and properties. (e.g., parallelism, perpendicula...rity, and congruency). Make a net to represent a three-dimensional object. Make a three-dimensional model from a net.[more]

Name concrete objects and pictures of three-dimensional solids. Identify models or illustrations of rectangular prisms, pyramids, and cylinders.And learn about faces, vertices, and edges of rectangular prisms.

Please make your comments on categories positive, and not just negative.

People work hard on educational categories, and we want to encourage them to make more!

Profanity (curse words), sexually suggestive remarks, and other such obviously inappropriate comments
will be deleted immediately, and are grounds for immediate expulsion. Remember, children use this website.

Personal criticism on project forums and in video content is not allowed and will be deleted immediately.
Any violations of this rule could result in expulsion from the project so please, no insults or other negative
personal remarks.

Very harshly-worded criticism of content will also be deleted promptly. Please use your vote to express your
harshest feelings. Repeated violations of this rule can result in expulsion. If you must criticize another
person's hard work, then be nice about it.
