New York State Learning Standards and Core Curriculum
NY-6.EE. Expressions, Equations and Inequalities
Apply and extend previous understandings of arithmetic to algebraic expressions.
NY-6.EE.2. Write, read, and evaluate expressions in which letters stand for numbers.
NY-6.EE.2a. Write expressions that record operations with numbers and with letters standing for numbers.
NY-6.EE.2b. Identify parts of an expression using mathematical terms (term, coefficient, sum, difference, product, factor and quotient); view one or more parts of an expression as a single entity.
NY-6.EE.2c. Evaluate expressions given specific values for their variables. Include expressions that arise from formulas in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order. (Order of Operations).
NY-6.EE.3. Apply the properties of operations to generate equivalent expressions.
Reason about and solve one-variable equations and inequalities.
NY-6.EE.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.
NY-6.EE.7. Solve real-world and mathematical problems by writing and solving equations of the form x + p = q; x – p = q; px = q; and ݑ/Űݑ= q for cases in which p, q and x are all nonnegative rational numbers, pݢɠ 0 and where x represents the unknown quantity.
