Maryland College and Career-Ready Standards
MD.MA.6.EE. Expressions and Equations (EE)
Apply and extend previous understandings of arithmetic to algebraic expressions.
6.EE.3. Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3(2+x) to produce the equivalent expression 6+3x; apply the distributive property to the expression 24x+18y to produce the equivalent expression 6(4x+3y); apply properties of operations to y+y+y to produce the equivalent expression 3y.
6.EE.3.1. Ability to use properties of operations to simplify expressions, therefore producing equivalent expressions.
Reason about and solve one-variable equations and inequalities.
6.EE.5. Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.
6.EE.5.1. See the skills and knowledge that are stated in the Standard.
6.EE.7. Solve real-world and mathematical problems by writing and solving equations of the form x+p = q and px = q for cases in which p, q and x are all non-negative rational numbers.
6.EE.7.2. Ability to develop conceptual understanding of inverse operations.
