Minnesota Standards
6.1.1.2
Compare positive rational numbers represented in various forms. Use the symbols < , = and >.
7.1.1.4
Compare positive and negative rational numbers expressed in various forms using the symbols < , > , = , ≤ , ≥ .
7.2.2.4
Represent real-world or mathematical situations using equations and inequalities involving variables and positive
and negative rational numbers.
8.2.3.2
Justify 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.
8.2.4.4
Use linear inequalities to represent relationships in various contexts.
8.2.4.5
Solve linear inequalities using properties of inequalities. Graph the solutions on a number line.
For example: The inequality -3x < 6 is equivalent to x > -2, which can be represented on the number line by shading
in the interval to the right of -2.
8.2.4.6
Represent 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.
