# Percent Change And Area Problems Worksheet

## 8 problems   Percent change is a measure of how much a value has changed over time. It is calculated as: (|(new value - old value) / old value|) x 100%

The percent change is expressed as a percentage, and it can be positive or negative. A positive percent change means that the new value is greater than the old value, and a negative percent change means that the new value is less than the old value.

For example, if the old value of a quantity is 50 and the new value is 55, the percent change is: (|(55 - 50) / 50|) x 100% = (5/50) x 100% = 10%

The percent change can be used to evaluate the change in a value over time, such as in stock market prices, population growth, and inflation.

Area, on the other hand, is the amount of space inside a two-dimensional object, like a rectangle or a circle. For example, the area of a rectangle can be calculated by multiplying the length by the width, and the area of a circle can be calculated by multiplying π (pi) by the radius squared.

## Teaching Percent change and area problems Easily

1. Guided practice: Provide students with guided practice problems using worksheets that involve percent change and area, starting with simple examples and gradually increasing the difficulty level.
2. Formative assessment: Continuously monitor student progress by using formative assessments such as quizzes, exit tickets, and class discussions. This can help identify areas where students need additional support..
3. Emphasize the importance: Emphasize the importance of percent change in evaluating the change in a value over time and how area is used to measure the space inside two-dimensional objects

## Why Should You Use Percent change and area problems Worksheet for your students?

1. Learning how to find percent error can help students understand the concept of accuracy and how to evaluate the accuracy of their own measurements and experiments.
2. Improving measurements and experiments: By understanding percent error, students can identify sources of error in their measurements and experiments and make adjustments to improve the accuracy of their results.
3. Real-world applications: Percent error is used in a variety of fields, including science, engineering, and technology. Learning how to find percent error can help students understand how the concept is used in real-world scenarios.
