6.EE.A.1 - Write and evaluate numerical expressions involving whole-number expressions.
6.EE.A.2 - Write, read, and evaluate expressions in which letters stand for numbers.
6.EE.A.2a - Write expressions that record operations with numbers and letters standing for numbers.
6.EE.A.2b - Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as single entity.
6.EE.A.2c - Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
6.EE.A.3 - Apply the properties of operations to generate equivalent expressions.
6.EE.A.4 - Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them).
6.EE.B.6 - Use variables to represent numbers and write expressions when solving a real-world or mathematical problem: understand that a variable can represent an unknown number, or depending on the purpose at hand, any number in a specified set.
