KS.6.EE. Expressions and Equations
Apply and extend previous understandings of arithmetic to algebraic expressions.
6.EE.2. Write, read, and evaluate expressions in which letters stand for numbers.
6.EE.2c. 6.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). For example, use the formulas ݑ = s^3 and ɰݐ = 6s^2 to find the volume and surface area of a cube with sides of length s = 1/2.
6.EE.3. Apply the properties of operations and combine like terms, with the conventions of algebraic notation, to identify and generate equivalent expressions. For example, apply the distributive property to the expression 3(2+ݑ) to produce the equivalent expression 6 + 3Űݑ; apply properties of operations to Űݑ + ưݑ + ưݑ to produce the equivalent expression 3y.
