AK.6.EE. Expressions and Equations
Apply and extend previous understandings of arithmetic to algebraic expressions.
6.EE.2. Write, read, and evaluate expressions in which letters stand for numbers.
6.EE.2.c. Evaluate expressions and formulas. Include formulas used in real-world problems. Perform arithmetic operations, including those involving whole number exponents, in the conventional order with or without parentheses. (Order of Operations)
6.EE.3. Apply the properties of operations to generate equivalent expressions. Model (e.g., manipulatives, graph paper) and apply the distributive, commutative, identity, and inverse properties with integers and variables by writing equivalent expressions. For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x.
