This interactive notes handout provides the is/of formula for calculating percentages with key words included to support student vocabulary acquisition! Students solve a sample problem for each type in order to have a model to use when working independently. Page 2 includes formulas for different types of percent problems, such as sales tax, discount, percent of change, and simple interest!

Use this at the beginning of a unit for instruction, throughout the unit for reference, or at the end of a unit for review!
