Calculating Percent Change Worksheet (Increase and Decrease)
Understanding percent change helps students compare values and see how quantities grow or shrink. This calculating percent change worksheet gives structured practice with both percent increase and percent decrease. It uses clear numerical examples instead of lengthy scenarios.
To calculate percent change, students subtract the starting value from the new value, divide by the starting value, and multiply by 100. This worksheet reinforces that process with simple number pairs, allowing students to focus on math rather than long word problems.
$$
\frac{\text{new value} – \text{starting value}}{\text{starting value}} \times 100
$$
The problems include a balanced mix of increases and decreases. Examples are moving from 20 to 30, 50 to 65, or 120 down to 96. Students must identify if the change is an increase or decrease and express the result as a percentage. This distinction is crucial and often confusing, but this worksheet clarifies it.
An answer key is included to support independent practice, homework checks, tutoring, or quick classroom reviews. This worksheet is great for upper elementary math, middle school percent units, and pre-algebra review, especially for students transitioning from basic percent problems to real-world applications.
Use this percent change worksheet as a stand-alone practice page, an assessment tool, or part of a unit on percentages, ratios, and proportional reasoning.
