Algebra
8.1 Algebra: Analyze and represent linear functions, and solve linear equations and systems of linear equations.8.1.1 Translate among contextual, verbal, tabular, graphical, and algebraic representations of linear functions. (Determining Slope , Graphs to Linear Equations , Graphs to Linear Equations 2 , Applied Linear Equations 1 , Applied Linear Equations 2 )
8.1.2 Determine the slope of a line and understand that it is a constant rate of change. (Determining Slope )
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. (Determining Slope )
8.1.4 Use linear functions and equations to represent, analyze and solve problems, and to make predictions and inferences. (Mixture Word Problems , Work Word Problems , Integer Word Problems , Algebraic Sentences 2 , Algebraic Sentences )
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.
Data Analysis and Algebra
8.2 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. (Mean, Median, Mode , Stem And Leaf Plots )
8.2.3 Interpret and analyze displays of data and descriptive statistics.
8.2.4 Compare descriptive statistics and evaluate how changes in data affect those statistics.
8.2.5 Describe the strengths and limitations of a particular statistical measure, and justify or critique its use in a given situation.
8.2.6 Use sample data to make predictions regarding a population.
8.2.7 Identify claims based on statistical data and evaluate the reasonableness of those claims.
8.2.8 Use data to estimate the likelihood of future events and evaluate the reasonableness of predictions. (Batting Averages )
Geometry and Measurement
8.3 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. (Identifying Angles , Congruent And Similar Triangles , Angle Measurements , Angle Measurements 2 , Proportions 2 )
8.3.2 Use models to show that the sum of the angles of any triangle is 180 degrees and apply this fact to find unknown angles. (Triangle Angles , Triangle Angles 2 , Solving For Angles )
8.3.3 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. (Quadrilateral Angles )
8.3.4 Use models to explore the validity of the Pythagorean Theorem, and use it to find missing lengths. (Pythagorean Theorem )
8.3.5 Apply the Pythagorean Theorem to find distances in a variety of 2- and 3-dimensional contexts, including distances on coordinate graphs. (Line Segments )
8.3.6 Use models and referents to explore and estimate square roots. (Estimating Square Roots , Perfect Squares )
