Slicing Three-Dimensional Figures – Playlist and Teaching Notes
In this playlist, students explore standard 7.G.A.3. They will describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids. Students will have the opportunity to practice identifying the resulting face shape when a solid is sliced parallel to its base, when a solid is sliced perpendicular to its base, and when a solid is sliced at an angle to its base. Students look at examples of three-dimensional figures and are guided through identifying the parts of the figures. Students also have the option to view instructional videos and complete practice quizzes or activities.

The playlist includes:
• 7 links to instructional videos or texts
• 2 links to practice quizzes or activities
• Definitions of key terms, such as cross-section and plane
• Visual examples of three-dimensional figures
• An example illustrating the parts of a three-dimensional figure

Accompanying Teaching Notes include:
• A review of key terminology
• Links to additional practice quizzes or activities on certain parts of the standard, such as slicing three-dimensional figures
• Links to video tutorials for students struggling with certain parts of the standard, such as determining the intersection of a solid and a plane
