National STEM Standards
STEM.M. MATHEMATICS: National Council of Teachers of Mathematics (NCTM)
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.
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.
4.2.3. Develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more-complex shapes.
NCTM.12. Connections to the Grade 6 Focal Points
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.
