OR.8.1.Algebra: Analyze and represent linear functions, and solve linear equations and systems of linear equations.
Algebra: Analyze and represent linear functions, and solve linear equations and systems of linear equations.
8.1.2. Determine the slope of a line and understand that it is a constant rate of change.
8.1.3. Identify and interpret the properties (i.e. slope, intercepts, continuity, and discreteness) of linear relationships as they are shown in the different representations and recognize proportional relationships ( y/x = k or y = kx ) as a special case.

8.1.5. Relate systems of two linear equations in two variables and their solutions to pairs of lines that are intersecting, parallel, or the same line.
8.1.6. Use informal strategies (e.g., graphs or tables) to solve problems involving systems of linear equations in two variables.
OR.8.2.Data Analysis and Algebra: Analyze and summarize data sets.
Data Analysis and Algebra: Analyze and summarize data sets.
8.2.1. Organize and display data (e.g., histograms, box-and-whisker plots, scatter plots) to pose and answer questions; and justify the reasonableness of the choice of display.
8.2.2. Use measures of center and spread to summarize and compare data sets.
8.2.3. Interpret and analyze displays of data and descriptive statistics.
OR.8.3.Geometry and Measurement: Analyze two- and three-dimensional spaces and figures by using distance and angle.
Geometry and Measurement: Analyze two- and three-dimensional spaces and figures by using distance and angle.
8.3.1. Use properties of parallel lines, transversals, and angles to find missing sides and angles, and to solve problems including determining similarity or congruence of triangles.
8.3.4. Use models to explore the validity of the Pythagorean Theorem, and use it to find missing lengths.
8.3.5. Apply the Pythagorean Theorem to find distances in a variety of 2- and 3-dimensional contexts, including distances on coordinate graphs.
8.3.6. Use models and referents to explore and estimate square roots. Quiz, Flash Cards, Worksheet, Game & Study Guide Real numbers
