7 Essential 7th Grade Math Review Worksheets
As a 7th grader, reviewing math concepts regularly is crucial to building a strong foundation for future math classes. Here are 7 essential 7th grade math review worksheets that cover key topics, along with explanations and examples to help you master each concept.
Worksheet 1: Fractions and Decimals Review
Fractions and decimals are fundamental concepts in 7th grade math. This worksheet reviews converting fractions to decimals, comparing fractions, and adding/subtracting fractions with like denominators.
| Problem | Solution |
|---|---|
| 1. Convert 3/4 to a decimal | 0.75 |
| 2. Compare 1/2 and 2/3 | 1/2 < 2/3 |
| 3. Add 1/4 + 1/4 | 2/4 or 1/2 |
Worksheet 2: Ratios and Proportional Relationships Review
Understanding ratios and proportional relationships is essential for solving problems involving scale drawings, similar figures, and percent increase/decrease.
- Ratios: A ratio is a comparison of two numbers. For example, 3:4 or 3⁄4.
- Proportional Relationships: A proportional relationship is a relationship between two quantities where one quantity changes at a constant rate in relation to the other.
Example: If a bike costs 80 and a bike helmet costs 20, what is the ratio of the bike’s cost to the helmet’s cost?
Solution: 80:20 or 4:1
Worksheet 3: Percent Review
Percent review is essential for understanding real-world applications, such as discounts, markups, and interest rates.
- Percent Increase: Find the difference between the original and new value, then divide by the original value.
- Percent Decrease: Find the difference between the original and new value, then divide by the original value.
Example: A shirt is on sale for 20% off its original price of $25. How much will you pay for the shirt?
Solution: 25 - (20% x 25) = 25 - 5 = $20
Worksheet 4: Algebraic Expressions Review
Algebraic expressions are used to solve equations and inequalities. Reviewing algebraic expressions helps you build a strong foundation for future math classes.
- Variables: Letters or symbols that represent unknown values.
- Constants: Numbers that do not change value.
Example: Simplify the expression 2x + 5 - 3x.
Solution: -x + 5
Worksheet 5: Geometry Review
Geometry review is essential for understanding shapes, measurements, and spatial reasoning.
- Points: A location in space, represented by a set of coordinates.
- Lines: A set of points extending infinitely in two directions.
- Angles: Formed by two rays sharing a common endpoint.
Example: What is the perimeter of a rectangle with a length of 6 cm and a width of 4 cm?
Solution: 2(l + w) = 2(6 + 4) = 20 cm
Worksheet 6: Data Analysis Review
Data analysis review helps you understand how to interpret and visualize data.
- Mean: The average value of a set of numbers.
- Median: The middle value of a set of numbers.
- Mode: The most frequently occurring value in a set of numbers.
Example: Find the mean, median, and mode of the following set of numbers: 2, 4, 6, 8, 10.
Solution:
- Mean: (2 + 4 + 6 + 8 + 10) / 5 = 6
- Median: 6
- Mode: No mode (since each value appears only once)
Worksheet 7: Word Problem Review
Word problem review helps you apply math concepts to real-world scenarios.
Example: Tom has 15 to spend on lunch. He buys a sandwich for 8 and a drink for $4. How much money does Tom have left?
Solution: 15 - 8 - 4 = 3
