Classify pyramids by their base shapes and lateral surface shapes. Classify three-dimensional figures by their attributes. Classify three-dimensional solids by their configuration and properties. (e.g., parallelism, perpendicularity, and congruency)

This two-minute Math Shorts episode helps students understand the two-dimensional figures that result from slicing solid three-dimensional figures. The video demonstrates this using cylinders and right rectangular pyramids as the three-dimensional fi...gures.

Common Core State Standards:
CCSS.Math.Cont.7.G.A.3 ( Grade 7 ): Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids[more]

Classify prisms 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, perpendicularity, and congruency)

Students can compare shapes by counting faces, edges, and vertices. Count faces, edges, and vertices to compare solid shapes. User clicks through the slides.

Tim Bedley, veteran teacher, gives a mini lesson to remind students how to identify straight edge, curved edge, flat face, curved face, vertex, vertices, base, circular base, etc. He uses an interactive board to define each one of these shapes. This ...is a great classroom resource to introduce or to review 3D shapes. (1:47)[more]

Identify properties of two- and three-dimensional figures. Investigate lines of symmetry and classification of figures based on their attributes in this study of Navajo hogans.

This video defines a prism as a 3D object with a face at one end identical to the face at the other end. Examples are shown on a computer screen with narration explaining how to identify each.
( 2:29)

Classify cones cylinders, and spheres by base shape and lateral surface shape. Identify the net (two-dimensional representation) that corresponds to a rectangular prism, cone, or cylinder. Recognize the three dimensional figure represented by a net.

Name concrete objects and pictures of three-dimensional cubes. Lesson goes through step-by-step at the learner's pace and even includes follow up activities.

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

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.
