Standard Description | Algebra: Analyze and represent linear functions and solve linear equations and systems of linear equations | Translate among contextual, verbal, tabular, graphical and algebraic representations of linear functions. | Determine the slope of a line and understand that it is a constant rate of change. | Identify and interpret the properties (ie 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. | Use linear functions and equations to represent, analyze and solve problems and to make predictions and inferences. | Relate systems of two linear equations in two variables and their solutions to pairs of lines that are intersecting, parallel or the same line. | Use informal strategies (eg graphs and tables) to solve problems involving systems of linear equations in two variables. | Data Analysis and Algebra: Analyze and summarize data sets | Organize and display data (eg histograms, box-and-whisker plots, scatter plots) to pose and answer questions; and justify the reasonableness of the choice of display. | Use measures of center and spread to summarize and compare sets. | Interpret and analyze displays of data and descriptive statistics | Compare descriptive statistics and evaluate how changes in data affect those statistics | Describe the strengths and limitations of a particular statistical measure and justify or critique its use in a given situation | Use data to make predictions regarding a population | Identify claims based on statistical data and evaluate the reasonableness of those claims. | Use data to estimate the likelihood of future events and evaluate the reasonableness of predictions. | Geometry and Measurement: Analyze two- and three-dimensional spaces and figures by using distance and angle. | 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. | Use models to show that the sum of the angles of any triangle is 180 degrees and apply this fact to find unknown angles. | Use models and logical arguments to show that the sum of the angles of any quadrilateral is 360 degrees and apply this fact to find unknown angles. | Use models to explore the validity of the Pythagorean Theorem and use it to find missing lengths. | Apply the Pythagorean Theorem to find distances in a variety of 2- and 3- dimensional contexts, including the distance on a coordinate grid. | Use models and referents to explore and estimate square roots. |
