Kentucky Academic Standards
Expressions and Equations
Cluster: Apply and extend previous understandings of arithmetic to algebraic expressions.
KY.6.EE.2. Write, read and evaluate expressions in which letters stand for numbers. (MP.1, MP.3, MP.4)
KY.6.EE.2.a. Write expressions that record operations with numbers and with letters standing for numbers.
KY.6.EE.2.c. Evaluate expressions for specific values of their variables, including values that are non-negative rational numbers. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
Cluster: Reason about and solve one-variable equation and inequalities.
KY.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. (MP.2, MP.6)
KY.6.EE.7. Solve real-world and mathematical problems by writing and solving equations of the form x+p=q and px=q for cases in which p, q and x are all nonnegative rational numbers. (MP.1, MP.2, MP.3, MP.4)
Cluster: Represent and analyze quantitative relationships between dependent and independent variables.
KY.6.EE.9. Use variables to represent two quantities in a real-world problem that changes in relationship to one another. (MP.3, MP.4, MP.7)
KY.6.EE.9.b. Write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable.
