Lesson reviewing the basics of percents and introducing percent change and complex percent word problems (from Pre-algebra, Algebra I, and Algebra II).

Goes over:

-Definition and concept of a percent

-Converting between fractions, decimals, and percents

-Calculating percents

-Shortcuts for calculating percents (memorizing easy percent to fraction conversions and “reversing” percent calculations).

-Difference between percent and percent change

-Converting percent changes into the appropriate decimal format

-Terminology related to percents/percent changes (discount, tax, tip, base salary, commission)

-General formula to use with percent word problems

-Using material above in tandem to interpret and solve complex percent word problems

Includes 11 walk-through examples.

The lesson focuses on building a solid foundation for students to better understand percentages. This product can be used to introduce percents to middle schoolers or to help high schoolers review the topic, with the overall objective to be able to solve these types of problems (and more complex versions) on the SAT. By the end, the student will be challenged to test their knowledge of percentages and to create new connections while solving real life application problems.
