9-12.1 Number Sense and Operation

9-12.1.1 Use multiple notations to perform and interpret the effects of operations on very large and very small numbers with and without technology.
9-12.1.2 Identify situations where estimation is appropriate and determine the degree of accuracy needed for a given problem situation (and the appropriate precision in which to report answers).
9-12.1.3 Given a representation of a number or expression, find equivalent representations using multiple notations (e.g., x to the 1/2 power vs. square root of x and visual representation of multiplying binomials).
9-12.1.4 Analyze and apply the properties of numbers and number systems.
9-12.1.5 Identify givens and unknowns in familiar and unfamiliar situations (e.g., finance, culture, including Montana American Indians, and nature) and describe relationships between variables.

9-12.2 Data Analysis

9-12.2.1 Select, create, and compare graphical or numerical representations of data sets using technology when appropriate. Reason about distributions using measures of central tendency and spread (e.g., percentiles, quartiles, inter-quartile range, and standard deviation).
9-12.2.2 Evaluate the validity of reports based on collected and/or published data by considering the source of the data, the design of the study, and the way data are displayed, analyzed, and interpreted.
- Statistics: Identifying biased samples (Algebra - JJ.3)
9-12.2.3 Make, evaluate, and justify decisions based on probabilities in multicultural situations, including those of Montana American Indians (e.g., finding expected value and using rules of probability).
9-12.2.4 Use technology as needed to determine the possible number of outcomes for an event or compound event using the fundamental counting principle, permutations, combinations, and other systematic counting methods.
9-12.2.5 Model two-variable data using curve fitting with and without technology. Write an equation for a given model and decide when or if predictions based on this equation are valid.
- Charts and graphs: Interpret a scatter plot (Algebra - N.6)
- Charts and graphs: Scatter plots: line of best fit (Algebra - N.7)

9-12.3 Geometric Reasoning

9-12.3.1 Formulate and evaluate conjectures about geometric objects and their properties, with and without technology, applying inductive reasoning when appropriate.
9-12.3.2 Use spatial reasoning and geometric models to solve problems with and without technology in the contexts of art, science, and culture, including Montana American Indians.
9-12.3.3 Identify, analyze, and use transformational, coordinate, and synthetic geometric approaches to solve problems.
9-12.3.4 Determine measures of two- and three-dimensional objects and their elements using trigonometric ratios, proportionality, the Pythagorean Theorem, and angle relationships.
9-12.3.5 Establish the validity of geometric conjectures using deductive reasoning, indirect proof, and counterexamples, and critique arguments made by others.

9-12.4 Algebraic and Functional Reasoning
