KS.6.EE. Expressions and Equations
Apply and extend previous understandings of arithmetic to algebraic expressions.
6.EE.3. Apply the properties of operations and combine like terms, with the conventions of algebraic notation, to identify and generate equivalent expressions. For example, apply the distributive property to the expression 3(2+ݑ) to produce the equivalent expression 6 + 3Űݑ; apply properties of operations to Űݑ + ưݑ + ưݑ to produce the equivalent expression 3y.
Reason about and solve one-variable equations and inequalities.
6.EE.4. 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.
