Nebraska Core Academic Content Standards
NE.MA.6.2. ALGEBRA: Students will communicate algebraic concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
MA.6.2.2. Algebraic Processes: Students will apply the operational properties when evaluating expressions and solving expressions, equations, and inequalities.
MA.6.2.2.b. Use substitution to determine if a given value for a variable makes an equation or inequality true.
MA.6.2.2.c. Evaluate numerical expressions, including absolute value and exponents, with respect to order of operations.
MA.6.2.2.d. Given the value of the variable, evaluate algebraic expressions (which may include absolute value) with respect to order of operations (non-negative rational numbers).
