Algebra & functions
Exponent rulesKnow and apply the properties of integer exponents to generate equivalent numerical expressions.220 questions →Graphing linear equationsConstruct a function to model a linear relationship between two quantities; determine the rate of change and initial value of the function.217 questions →Linear coefficient interpretationsConstruct a function to model a linear relationship between two quantities; determine the rate of change and initial value of the function.10 questions →Modeling linear situationsConstruct a function to model a linear relationship between two quantities; determine the rate of change and initial value of the function.10 questions →Scientific notationUse numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities.15 questions →Slope formulaConstruct a function to model a linear relationship between two quantities; determine the rate of change and initial value of the function.15 questions →Square roots and cube rootsUse square root and cube root symbols to represent solutions to equations of the form x² = p and x³ = p, where p is a positive rational number.15 questions →
Geometry & measurement
Distance formulaApply the Pythagorean Theorem to find the distance between two points in a coordinate system.15 questions →Polygon angle formulasUse informal arguments to establish facts about the angle sum and exterior angle of triangles, and about the angles created when parallel lines are cut by a transversal.15 questions →Pythagorean theoremApply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.15 questions →Similar triangle shadows (SAT)Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations.10 questions →
Statistics & probability
Scatter plots and bivariate dataConstruct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities.22 questions →Scatterplots and trend linesUse the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept.18 questions →Two-way tablesUnderstand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table.15 questions →
