U.S. National Standards
N.3. Geometry (NCTM)
3.2. Specify locations and describe spatial relationships using coordinate geometry and other representational systems.
3.2.1. Use coordinate geometry to represent and examine the properties of geometric shapes.
3.2.2. Use coordinate geometry to examine special geometric shapes, such as regular polygons or those with pairs of parallel or perpendicular sides.
3.4. Use visualization, spatial reasoning, and geometric modeling to solve problems.
3.4.4. Use geometric models to represent and explain numerical and algebraic relationships.
N.4. Measurement (NCTM)
4.2. Apply appropriate techniques, tools, and formulas to determine measurements.
4.2.2. Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.
N.12. Connections to the Grade 6 Focal Points (NCTM)
12.3. Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
