Oregon Standards - Grade 8 Math
The state of Oregon has prescribed that students of Grade 8 Math master certain topics. The topics are listed below. Each of these topics/strands are covered in TenMarks, helping students refresh their knowledge, as well as learn as they practice - resulting in mastery.
|
8.1: 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.
|
|
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.
|
|
8.1.4 Use linear functions and equations to represent, analyze and solve problems, and to make predictions and inferences.
|
|
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.
|
|
8.2: 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.
|
|
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.
|
|
8.3: 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.
|
|
8.3.2 Use models to show that the sum of the angles of any triangle is 180 degrees and apply this fact to find unknown angles.
|
|
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.
|
|
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.
