Print Lesson PlanOverview
In this Cyberchase activity, students learn about two-dimensional and three-dimensional shapes. Students watch a video clip and then identify the shapes that they see in the clip. In Assessment A, students are asked to identify shapes. In Assessment B, they have the opportunity to create a three-dimensional shape from a cutout.

The Lesson
Part I: Learning Activity
1. Read the following to your students: "In this video clip, a young friend of Bianca's teaches her about crystals. She learns how different crystals are made of 3-D, or three dimensional, shapes. On the handout there is a list of different shapes with a picture of each. Some are two-dimensional and some are three-dimensional. As you watch the video, circle any of the shapes you see in the crystals." (Note: You can review these shapes before playing the video clip and answer any questions students have about vocabulary, etc.)
2. Discuss the difference between two-dimensional and three-dimensional with the class by eliciting student ideas.
3. Distribute Identifying Shapes in Crystals Handout .
4. Tell the students that they will now view the video clip in which Bianca and her friend learn about crystals. Tell students to focus their attention on the 2-D and 3-D shapes they see and ask them to pay special attention to any embedded shapes they see inside of the 3-D shapes.
5. Play the Making Rock Candy QuickTime Video.
6. Discuss which shapes the students saw in the video. Ask students if they noticed the connections between 2-D and 3-D shapes.
Part II: Assessment
Assessment: Level A (proficiency): Students will match a variety of shapes with the correct name of the shape.
Assessment: Level B (above proficiency): Students will cut out and fold measured shapes (also called networks) into common 3-D shapes.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.Media Resources Used in this Lesson:
