6.EE.2c. Evaluate expressions at specific values of their variables. Include expressions that arise from the 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 V=s3 and A=6s2 to find the volume and surface area of a cube with sides of lengths s=1/2.
This PPT uses the formulas mentioned in the CC standard above. There are 9 multiple choice problems in all using real-world situations.
