U.S. National Standards

N.3. Geometry (NCTM)
3.1. Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships.
3.1.1. Precisely describe, classify, and understand relationships among types of two- and three-dimensional objects using their defining properties.
3.1.3. Create and critique inductive and deductive arguments concerning geometric ideas and relationships, such as congruence, similarity, and the Pythagorean relationship.
N.4. Measurement (NCTM)
4.1. Understand measurable attributes of objects and the units, systems, and processes of measurement.
4.1.3. Understand, select, and use units of appropriate size and type to measure angles, perimeter, area, surface area, and volume.
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 7 Focal Points (NCTM)
12.3. Data Analysis: Students use proportions to make estimates relating to a population on the basis of a sample. They apply percentages to make and interpret histograms and circle graphs.
