About Percent Change
Proportional Relationships deepens students' understanding of ratios into a full algebraic framework. Students identify the constant of proportionality, distinguish proportional from non-proportional relationships, apply scale drawings, calculate percent change, and use the simple interest formula. This topic bridges the ratio work of Grade 6 and the linear functions of Grades 8 and 9.
Percent change is one of the most widely reported statistics in news and business — population growth, stock market changes, price increases. Understanding it makes students informed citizens who can evaluate numerical claims critically.
What Your Child Will Learn
- Calculate percent increase using the formula (new − original) / original × 100
- Calculate percent decrease using the same formula
- Apply percent change to real-world situations including markups and markdowns
- Determine whether a change is an increase or decrease before applying the formula
- Interpret a percent change value in the context of a real-world problem
