WV.M.6.EE. Expressions and Equations
Apply and extend previous understandings of arithmetic to algebraic expressions.
M.6.12. Write and evaluate numerical expressions involving whole-number exponents.
M.6.13. Write, read and evaluate expressions in which letters stand for numbers.
M.6.13.b. 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. (e.g., Describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.)
M.6.14. Apply the properties of operations to generate equivalent expressions (e.g., 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).
