MD.1.0. Knowledge of Algebra, Patterns, and Functions: Students will algebraically represent, model, analyze, or solve mathematical or real-world problems involving patterns or functional relationships.
1.B.1. Expressions, Equations, and Inequalities: Write, simplify, and evaluate expressions.
1.B.1.a. Write an algebraic expression to represent unknown quantities (Assessment limit: Use one unknown and no more than 3 operations and rational numbers (-1000 to 1000)).
1.B.1.d. Simplify algebraic expressions by combining like terms (Assessment limit: Use no more than 3 variables with integers (-50 to 50), or proper fractions with denominators as factors of 20 (-20 to 20)).
1.B.2. Expressions, Equations, and Inequalities: Identify, write, solve, and apply equations and inequalities.
1.B.2.a. Write equations or inequalities to represent relationships (Assessment limit Use a variable, the appropriate relational symbols (>, is greater than or equal to, <, is less than or equal to, =), and no more than 3 operational symbols (+, -, x, /) on either side and rational numbers (-1000 to 1000)).
1.B.2.d. Identify or graph solutions of inequalities on a number line (Assessment limit: Use one variable once with a positive whole number coefficient and integers (-100 to 100)).
1.B.2.g. Write equations and inequalities that describe real-world problems.
