CCSS.Math.Content.6.EE.A.2c
The Standard
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).

What This Standard Means
What Students Need to Do
- Students replace variables with given values and calculate the result. They use exponents and the order of operations correctly, including when working with real-world formulas.
What Mastery Looks Like
- Students correctly substitute a given number for each variable and follow the order of operations. They can use a formula, show the intermediate steps, and label a real-world answer with appropriate units.
Common Misconceptions
- Students may replace the variable but ignore the exponent, such as reading 4² as 4 × 2. They may also multiply before evaluating the exponent or apply an exponent to a coefficient that is not part of the base.
How to Assess It
- Exit ticket: A cube has side length 3 cm. Use V = s³ and A = 6s² to find its volume and surface area, showing each substitution.

Ways to Teach It
Build a cube with snap cubes, then use its side length to calculate volume and surface area before checking by counting cubes and faces.
Ask students to explain why 6s² with s = 4 means 6 × 4², not 24².
Give pairs of students cards showing expressions, variable values, and answers, then have them match each complete set.
Use C = 12 + 3h to calculate bicycle rental costs for several numbers of hours and compare the results in a table.
