GA.MGSE6.EE. Expressions and Equations
Apply and extend previous understandings of arithmetic to algebraic expressions.
MGSE6.EE.2. Write, read, and evaluate expressions in which letters stand for numbers.
MGSE6.EE.2a. Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation “Subtract y from 5” as 5–y.
MGSE6.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. For example, 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.
MGSE6.EE.2c. Evaluate expressions at 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 when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V=s^3 and A=6s^2 to find the volume and surface area of a cube with sides of length s=1/2.
MGSE6.EE.3. Apply the properties of operations to generate equivalent expressions. For example, 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.
Reason about and solve one-variable equations and inequalities.
MGSE6.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.
MGSE6.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.
Represent and analyze quantitative relationships between dependent and independent variables.
MGSE6.EE.9. Use variables to represent two quantities in a real-world problem that change in relationship to one another.
MGSE6.EE.9a. Write an equation to express one quantity, the dependent variable, in terms of the other quantity, the independent variable.
