Minnesota Grade 8 Math Standards
The official Minnesota Grade 8 math standards, grouped by domain with the exact code and description for each expectation.
8.1
- 8.1.1.1Classify real numbers as rational or irrational. Know that when a square root of a positive integer is not an integer, then it is irrational. Know that the sum of a rational number and an irrational number is irrational, and the product of a non-zero rational number and an irrational number is irrational
- 8.1.1.2Compare real numbers; locate real numbers on a number line. Identify the square root of a positive integer as an integer, or if it is not an integer, locate it as a real number between two consecutive positive integers
- 8.1.1.3Determine rational approximations for solutions to problems involving real numbers
- 8.1.1.4Know and apply the properties of positive and negative integer exponents to generate equivalent numerical expressions
- 8.1.1.5Express approximations of very large and very small numbers using scientific notation; understand how calculators display numbers in scientific notation. Multiply and divide numbers expressed in scientific notation, express the answer in scientific notation, using the correct number of significant digits when physical measurements are involved
8.2
- 8.2.1.1Understand that a function is a relationship between an independent variable and a dependent variable in which the value of the independent variable determines the value of the dependent variable. Use functional notation, such as f(x), to represent such relationships
- 8.2.1.2Use linear functions to represent relationships in which changing the input variable by some amount leads to a change in the output variable that is a constant times that amount
- 8.2.1.3Understand that a function is linear if it can be expressed in the form f(x) =mx+bor if its graph is a straight line
- 8.2.1.4Understand that an arithmetic sequence is a linear function that can be expressed in the form f(x) =mx+b, wherex= 0, 1, 2, 3, …
- 8.2.1.5Understand that a geometric sequence is a non-linear function that can be expressed in the form f(x) =abto thexpower, wherex= 0, 1, 2, 3, …
- 8.2.2.1Represent linear functions with tables, verbal descriptions, symbols, equations and graphs; translate from one representation to another
- 8.2.2.2Identify graphical properties of linear functions including slopes and intercepts. Know that the slope equals the rate of change, and that the y-intercept is zero when the function represents a proportional relationship
- 8.2.2.3Identify how coefficient changes in the equation f(x) =mx+baffect the graphs of linear functions. Know how to use graphing technology to examine these effects
- 8.2.2.4Represent arithmetic sequences using equations, tables, graphs and verbal descriptions, and use them to solve problems
- 8.2.2.5Represent geometric sequences using equations, tables, graphs and verbal descriptions, and use them to solve problems
- 8.2.3.1Evaluate algebraic expressions, including expressions containing radicals and absolute values, at specified values of their variables
- 8.2.3.2Justify steps in generating equivalent expressions by identifying the properties used, including the properties of algebra. Properties include the associative, commutative and distributive laws, and the order of operations, including grouping symbols
- 8.2.4.1Use linear equations to represent situations involving a constant rate of change, including proportional and non-proportional relationships
- 8.2.4.2Solve multi-step equations in one variable. Solve for one variable in a multi-variable equation in terms of the other variables. Justify the steps by identifying the properties of equalities used
- 8.2.4.3Express linear equations in slope-intercept, point-slope and standard forms, and convert between these forms. Given sufficient information, find an equation of a line
- 8.2.4.4Use linear inequalities to represent relationships in various contexts
- 8.2.4.5Solve linear inequalities using properties of inequalities. Graph the solutions on a number line
- 8.2.4.6Represent relationships in various contexts with equations and inequalities involving the absolute value of a linear expression. Solve such equations and inequalities and graph the solutions on a number line
- 8.2.4.7Represent relationships in various contexts using systems of linear equations. Solve systems of linear equations in two variables symbolically, graphically and numerically
- 8.2.4.8Understand that a system of linear equations may have no solution, one solution, or an infinite number of solutions. Relate the number of solutions to pairs of lines that are intersecting, parallel or identical. Check whether a pair of numbers satisfies a system of two linear equations in two unknowns by substituting the numbers into both equations
- 8.2.4.9Use the relationship between square roots and squares of a number to solve problems
8.3
- 8.3.1.1Use the Pythagorean theorem to solve problems involving right triangles
- 8.3.1.2Determine the distance between two points on a horizontal or vertical line in a coordinate system. Use the Pythagorean theorem to find the distance between any two points in a coordinate system
- 8.3.1.3Informally justify the Pythagorean theorem by using measurements, diagrams and computer software
- 8.3.2.1Understand and apply the relationships between the slopes of parallel lines and between the slopes of perpendicular lines. Dynamic graphing software may be used to examine these relationships
- 8.3.2.2Analyze polygons on a coordinate system by determining the slopes of their sides
- 8.3.2.3Given a line on a coordinate system and the coordinates of a point not on the line, find lines through that point that are parallel and perpendicular to the given line, symbolically and graphically
8.4
- 8.4.1.1Collect, display and interpret data using scatterplots. Use the shape of the scatterplot to informally estimate a line of best fit and determine an equation for the line. Use appropriate titles, labels and units. Know how to use graphing technology to display scatterplots and corresponding lines of best fit
- 8.4.1.2Use a line of best fit to make statements about approximate rate of change and to make predictions about values not in the original data set
- 8.4.1.3Assess the reasonableness of predictions using scatterplots by interpreting them in the original context
