Unit 5: Geometry
7th grade Mathematics
7th Grade Comprehensive Course Overview
• Located on the 6-8 math section of www.georgiastandards.org
• Designed to provide clarification of CCGPS Mathematics Standards
• Organized to link together many sources of information pertinent to CCGPS 7th Grade Standards
• The comprehensive course overviews in grades 6-8 are similar to “grade level overviews” in K-5. They have been created for Coordinate Algebra and Analytic Geometry as well, making them a great tool for vertical alignment.
Rationale for Unit 5 RevisionsPrior to Revisions After Revisions
The introductory segment was too lengthy and not “teacher-friendly”; could not be consumed efficiently, so many teachers would skip this section.
Differentiation suggestions have been incorporated for both enrichment and remediation
Some standards were overrepresented by multiple tasks while other standards had no aligned task.
Some tasks were removed or heavily edited in order to increase rigor and clarity while others were created.
Many of the student versions of tasks needed more clarity in directions and more structure to help guide student responses.

Task Table Notes
Unit 5 Tasks
The Unit 5 Tasks Primarily Address:– Developing understanding for cross sections formed by slicing
three-dimensional figures– Understanding the relationship between circumference and area– Finding missing angles using angle relationships– Using volume formulas in real-world contexts
Purpose of the Tasks
• Provide Opportunities for Problem-Based Learning– Examples: Check out Dan Meyer, Robert Kaplinksy’s
websites
• Provide several entry points to the standards.• Teachers should review all tasks in a given unit to
determine which tasks would be appropriate for their students. Tasks can be adapted to fit the needs or your classroom. Most standards are covered by various tasks.

Just A Friendly Reminder…
The Unit 5 Frameworks are meant to be seen as GUIDELINES
– Take from the frameworks what you need for your students to be successful
– Note that there are more tasks included within the unit
– It is not feasible nor expected to complete all of the assigned tasks within an academic year
MCC7.G.6 Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.

Unit 5 Challenges
Surface Area Volume
Triangular Right Prism Yes Yes
Hexagonal Right Prism Yes Yes
Rectangular Right Prism Yes Yes
Cylinder No No
Pyramid Yes No
Cone No No
MCC7.G.6 Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
Volume of cylinder and cone are specifically addressed in MCC.8.G.9 along with spheres.
Surface Area of a cylinder and cone is never specifically mentioned in the standards, though can be determined when students have the required prerequisites.
