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. ( 8:10)[more]

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.

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]

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. ( 2:52)

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).

Learn the names of the 3-d shapes and see real world examples of each. Cubes, triangular prisms, cones and cylinders. Slide show accompanied by music. Names of shapes appear on the screen.

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]

Mrs. Rice and Ms. Reppert name some 3D shapes. The teachers explain that 3D shapes have sides and faces. They name the shape and then have to name something in real life with the same shape. This is a great resource to help students master this impor...tant skill. (4:16)[more]
