STANDARDS MCC6.EE.1 - Write and evaluate expressions involving whole-number exponents. MCC6.EE.2- Write, read, and evaluate expressions in which letters stand for numbers.MCC6.EE.2a - Write expressions that record operations with numbers and with letters standing for numbers. MCC6.EE.2b - Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. MCC6.EE.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). MCC6.EE.3 - Apply the properties of operations to generate equivalent expressions. MCC6.EE.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.)
