What crucial skills will you develop regarding the number system in 7th grade math? You’ll delve into the world of rational numbers, understanding how to perform operations with fractions, decimals, and percentages. This involves adding, subtracting, multiplying, and dividing both positive and negative numbers, as well as interpreting absolute value.
In 7th grade, students gain a comprehensive understanding of rational numbers, which is a cornerstone for future math studies. According to the National Council of Teachers of Mathematics (NCTM), a strong foundation in number sense is critical for success in algebra and beyond. Mastering rational numbers means students can confidently work with fractions, decimals, and percentages, understanding their relationships and applications in real-world scenarios.
1.1. Working with Rational Numbers
What are rational numbers, and how do you manipulate them? Rational numbers are numbers that can be expressed as a fraction p/q, where p and q are integers and q is not zero. You will learn to perform all four basic operations (addition, subtraction, multiplication, and division) with these numbers.
1.1.1. Adding and Subtracting Fractions
How do you add and subtract fractions with different denominators? To add or subtract fractions, they must have a common denominator. The process involves finding the least common multiple (LCM) of the denominators and converting each fraction to an equivalent fraction with the LCM as the new denominator. For example, to add 1/3 and 1/4, the LCM of 3 and 4 is 12. So, 1/3 becomes 4/12 and 1/4 becomes 3/12. Adding these gives 7/12. This concept is detailed in “Developing Number Concepts” by Kathy Richardson, which emphasizes hands-on activities to build a strong understanding of fractions.
1.1.2. Multiplying and Dividing Fractions
How do you multiply and divide fractions efficiently? Multiplying fractions involves multiplying the numerators together and the denominators together. Dividing fractions requires inverting the second fraction (the divisor) and then multiplying. For instance, to multiply 2/3 by 3/4, you multiply 2 3 to get 6 and 3 4 to get 12, resulting in 6/12, which simplifies to 1/2. To divide 2/3 by 3/4, you invert 3/4 to get 4/3, then multiply 2/3 by 4/3, resulting in 8/9. Swapping from multiplication to division using reciprocals can significantly improve your understanding and speed, as noted in a study by the University of Chicago School Mathematics Project.
1.2. Decimals and Percentages
How do decimals and percentages relate to fractions, and how do you convert between them? Decimals and percentages are alternative ways of expressing fractions. A decimal is a fraction with a denominator that is a power of 10, while a percentage is a fraction with a denominator of 100. To convert a fraction to a decimal, divide the numerator by the denominator. To convert a decimal to a percentage, multiply by 100.
1.2.1. Converting Fractions to Decimals and Percentages
What’s the easiest method to convert fractions into decimals and percentages? To convert a fraction to a decimal, perform long division. For example, to convert 3/4 to a decimal, divide 3 by 4, resulting in 0.75. To convert this decimal to a percentage, multiply by 100, giving 75%.
1.2.2. Applying Percentages in Real-World Scenarios
How can you use percentages to solve practical problems? Percentages are commonly used in real-world scenarios such as calculating discounts, sales tax, and interest rates. To find a percentage of a number, convert the percentage to a decimal and multiply by the number. For example, to find 20% of 50, convert 20% to 0.20 and multiply by 50, resulting in 10. According to a report by the U.S. Department of Education, understanding percentages is essential for financial literacy and making informed decisions.
1.3. Positive and Negative Numbers
Why is understanding positive and negative numbers important in math? Positive and negative numbers are essential for representing quantities that can be both above and below zero, such as temperature, elevation, and financial transactions.
1.3.1. Performing Operations with Signed Numbers
How do you perform addition, subtraction, multiplication, and division with positive and negative numbers?
- Addition: When adding numbers with the same sign, add their absolute values and keep the sign. When adding numbers with different signs, subtract their absolute values and take the sign of the number with the larger absolute value.
- Subtraction: To subtract a number, add its opposite. For example, a – b = a + (-b).
- Multiplication and Division: When multiplying or dividing numbers with the same sign, the result is positive. When multiplying or dividing numbers with different signs, the result is negative.
A study by Stanford University’s Graduate School of Education found that using visual aids, such as number lines, significantly improves students’ understanding of signed number operations.
1.3.2. Interpreting Absolute Value
What does absolute value mean, and how is it used? The absolute value of a number is its distance from zero on the number line, regardless of direction. It is always non-negative. For example, the absolute value of -5 is 5, denoted as |-5| = 5. Absolute value is used to find the magnitude of a number without considering its sign, which is useful in various applications, such as calculating distances and errors.

2. Expressions and Equations: A Gateway to Algebra
What foundational skills will you gain in expressions and equations during 7th grade math? You’ll transition into the realm of algebra by learning to use variables, solve multi-step equations, and represent inequalities graphically. These skills are crucial for future math courses.
2.1. Using Variables
How are variables used to represent unknown quantities? Variables are symbols, usually letters, that represent unknown quantities in algebraic expressions and equations. They allow you to express relationships between numbers and solve for unknowns.
2.1.1. Writing Algebraic Expressions
How do you translate word problems into algebraic expressions? To write algebraic expressions, identify the unknown quantities and represent them with variables. Use mathematical operations to express the relationships described in the word problem. For example, “five more than a number” can be written as x + 5, where x represents the unknown number. According to research from the University of California, Berkeley, students who practice translating word problems into algebraic expressions perform better in algebra.
2.1.2. Evaluating Expressions
What does it mean to evaluate an algebraic expression, and how do you do it? Evaluating an expression involves substituting specific values for the variables and simplifying the expression using the order of operations (PEMDAS/BODMAS). For example, to evaluate 3x + 2 when x = 4, substitute 4 for x to get 3(4) + 2, which simplifies to 12 + 2 = 14.
2.2. Solving Multi-Step Equations
What are multi-step equations, and how do you solve them? Multi-step equations involve more than one operation and require multiple steps to isolate the variable. The key is to perform inverse operations in the correct order to undo the operations acting on the variable.
2.2.1. Using Inverse Operations
How do you use inverse operations to isolate a variable? Inverse operations are operations that undo each other. For example, addition and subtraction are inverse operations, as are multiplication and division. To solve an equation, apply inverse operations to both sides of the equation to isolate the variable. For example, to solve 2x + 3 = 7, subtract 3 from both sides to get 2x = 4, then divide by 2 to get x = 2. A study by the National Research Council found that students who understand the concept of inverse operations are more successful in solving algebraic equations.
2.2.2. Solving Real-World Problems
How can you apply multi-step equations to solve real-world problems? Many real-world problems can be modeled with multi-step equations. Translate the problem into an equation, then solve for the unknown variable. For example, “A taxi charges $2.50 plus $0.20 per mile. If a ride costs $9.30, how many miles was the ride?” The equation is 2.50 + 0.20m = 9.30. Subtracting 2.50 from both sides gives 0.20m = 6.80. Dividing by 0.20 gives m = 34 miles.
2.3. Understanding and Graphing Inequalities
What are inequalities, and how do they differ from equations? Inequalities are mathematical statements that compare two expressions using symbols like >, <, ≥, and ≤. Unlike equations, which have a single solution, inequalities have a range of solutions.
2.3.1. Representing Inequalities on a Number Line
How do you graph inequalities on a number line? To graph an inequality, draw a number line and use an open circle for < and > (indicating the endpoint is not included) or a closed circle for ≤ and ≥ (indicating the endpoint is included). Shade the region of the number line that represents the solutions to the inequality. For example, to graph x > 3, draw an open circle at 3 and shade the region to the right.
2.3.2. Solving and Graphing Linear Inequalities
How do you solve and graph linear inequalities? Solving linear inequalities is similar to solving linear equations, but with one important difference: when multiplying or dividing both sides by a negative number, you must reverse the inequality sign. For example, to solve -2x < 6, divide by -2 and reverse the sign to get x > -3. The graph would have an open circle at -3 and shade to the right. According to research by the Center for Mathematics Education, students who practice graphing inequalities develop a deeper understanding of their solutions.

4.1. Defining Functions
What is a function, and what are its key characteristics? A function is a relationship between two sets of elements, where each input (x-value) has exactly one output (y-value). This relationship is often expressed as y = f(x), where f is the function, x is the input, and y is the output.
4.1.1. Understanding Input and Output
How do input and output relate in a function? The input is the value you put into the function, and the output is the result you get after applying the function’s rule. For example, if f(x) = 2x + 1, then when x = 3, the output is f(3) = 2(3) + 1 = 7. Therefore, the input is 3, and the output is 7.
4.1.2. Identifying Functions
How can you determine if a relationship is a function? A relationship is a function if each input has exactly one output. This can be verified using the vertical line test on a graph: if any vertical line intersects the graph more than once, the relationship is not a function. According to research from MIT, understanding this definition is crucial for grasping advanced mathematical concepts.
4.2. Comparing Functions
How can you compare different functions? Functions can be compared algebraically, graphically, numerically in tables, or by verbal descriptions.
4.2.1. Algebraic Comparison
How do you compare functions using equations? By examining their equations, you can identify differences in their rates of change and initial values. For example, comparing f(x) = 2x + 3 and g(x) = 3x + 1, we see that g(x) has a steeper slope (3) than f(x) (2), but f(x) has a higher initial value (3) than g(x) (1).
4.2.2. Graphical Comparison
How do you compare functions using graphs? By plotting the graphs of different functions on the same coordinate plane, you can visually compare their behavior, including their slopes, intercepts, and turning points.
4.2.3. Numerical Comparison
How do you compare functions using tables? By creating tables of values for different functions, you can compare their outputs for the same inputs and identify patterns and trends.
4.3. Evaluating Functions
How do you evaluate a function for a given input? Evaluating a function involves substituting a specific value for the input variable and calculating the corresponding output.
4.3.1. Using Function Notation
How do you use function notation to evaluate functions? Function notation, such as f(x), provides a concise way to represent and evaluate functions. For example, to evaluate f(x) = x^2 – 2x + 1 at x = 3, you would write f(3) = (3)^2 – 2(3) + 1 = 9 – 6 + 1 = 4.
4.3.2. Applying Functions in Real-World Scenarios
How can you use functions to model real-world relationships? Functions can be used to model a wide range of real-world relationships, such as the relationship between time and distance, or the relationship between the number of items sold and the revenue generated. For example, if the cost of producing x items is given by the function C(x) = 5x + 100, then the cost of producing 20 items is C(20) = 5(20) + 100 = $200.

5.1.2. Defining Rates
What are rates, and how are they expressed with units? A rate is a ratio that compares two quantities with different units. For example, speed is a rate that compares distance traveled to time taken, such as 60 miles per hour (60 mph). According to the Bureau of Labor Statistics, understanding rates is crucial for many occupations, including transportation and logistics.
5.2. Solving Proportionality Problems
How can you solve problems involving proportional relationships? Proportionality involves two quantities that vary directly with each other. If y is proportional to x, then y = kx, where k is the constant of proportionality.
5.2.1. Identifying Proportional Relationships
How do you determine if two quantities are proportional? Two quantities are proportional if their ratio is constant. For example, if the cost of buying apples is proportional to the number of apples purchased, then the ratio of cost to number of apples remains constant.
5.2.2. Using Cross-Multiplication
How can you use cross-multiplication to solve proportions? Cross-multiplication is a technique used to solve proportions, which are equations stating that two ratios are equal. If a/b = c/d, then ad = bc. This technique is widely used in solving real-world problems involving proportions, such as scaling recipes or converting units.
5.3. Applying Proportionality to Percentages
How are proportionality and percentages related? Percentages can be thought of as proportions out of 100. Therefore, problems involving percentages can be solved using proportional reasoning.
5.3.1. Finding a Percentage of a Quantity
How do you calculate a percentage of a given quantity? To find a percentage of a quantity, convert the percentage to a decimal and multiply by the quantity. For example, to find 25% of 80, convert 25% to 0.25 and multiply by 80, resulting in 20.
5.3.2. Finding the Whole Given a Percentage
How can you find the whole amount when given a percentage and part of the whole? If you know a percentage and the part of the whole it represents, you can use proportional reasoning to find the whole amount. For example, if 15 is 30% of a number, then you can set up the proportion 15/x = 30/100 and solve for x using cross-multiplication, resulting in x = 50.

7.1.1. Slope-Intercept Form
What is the slope-intercept form of a linear equation, and why is it useful? The slope-intercept form (y = mx + b) is useful because it directly shows the slope (m) and the y-intercept (b) of the line. The slope represents the rate of change of y with respect to x, and the y-intercept is the point where the line crosses the y-axis.
7.1.2. Graphing Linear Equations
How do you graph a linear equation given its equation? To graph a linear equation, you can plot two points and draw a line through them. A common method is to find the y-intercept (by setting x = 0) and another point (by setting y = 0 or choosing another convenient value for x). Alternatively, you can use the slope-intercept form to plot the y-intercept and then use the slope to find another point.
7.2. Finding the Slope of a Line
How do you find the slope of a line from a table, graph, or equation? The slope of a line measures its steepness and direction. It can be found using different methods depending on the given information.
7.2.1. Slope from a Graph
How do you determine the slope of a line from its graph? The slope of a line can be found from its graph by calculating the rise over run between any two points on the line. Rise is the vertical change, and run is the horizontal change. The formula for slope is m = (y2 – y1) / (x2 – x1).
7.2.2. Slope from a Table
How do you calculate the slope of a line from a table of values? If you have a table of values for x and y, you can choose any two points (x1, y1) and (x2, y2) from the table and use the formula m = (y2 – y1) / (x2 – x1) to find the slope.
7.2.3. Slope from an Equation
