These activity sheets teach your students how to calculate the percent change between two values.

#### In mathematics, there is a huge list of various operations to solve questions such as addition, subtraction, In multiplication, division, and so on. Among these, a very operation that is often used in different places multiple times in mathematics is the percentage. Do you know what it is? Well, don't worry! Let's find out what the percentage is! The word percentage roots from the Latin word per centum, meaning per hundred. In math, a percentage is defined as a fraction that is expressed as a number out of 100. The % symbol denotes the number expressed in percentage. Now that we know what percentages are, let's take a look at what percentage of change means. When two values that are expressed in hundredths are compared, the comparison is known as percentage of change. A negative percent of change indicates a decrease from the original value to the second value. A positive percent of change indicates an increase from the original value to the second value.

When an amount of anything changes over time we often want to understand how big the change was. This happens very often in the financial world to help us gauge our trajectory. Is our business failing or succeeding? Percentage of change tells us this. There are two methods for determining percentage of change. Method 1 is to subtract the old value from the new value and then divide that by the old value. To convert it to a percentage just multiply it by one hundred. Method 2 is to divide the new value by the old value and multiply it by one hundred. You would finish that off by subtracting one hundred percent. Your students will use these worksheets to learn how to calculate the percent change between two values. Changes may be positive (addition) or negative (subtraction). All necessary formulas have been included.
