What Do You Learn in 6th Grade Math?

In 6th grade math, students learn about fundamental concepts including fractions, decimals, percentages, basic algebra, and geometry. They also develop problem-solving and critical thinking skills through more advanced arithmetic and introduction to data analysis.


Sixth-grade math is a critical milestone in a student’s mathematical journey. It bridges the gap between elementary arithmetic and more advanced mathematical concepts, laying a solid foundation for future mathematical endeavors.

In this comprehensive guide, we will explore the diverse and essential topics covered in 6th-grade math, providing a detailed overview of each area and offering illustrative examples with step-by-step solutions to aid in understanding.

Number Sense and Operations

In 6th grade math, students delve into the concept of place value, gaining a deeper understanding of how digits in multi-digit numbers relate to each other and their respective values. They also learn to identify factors and multiples, enhancing their ability to work with different numbers in various mathematical operations.

Additionally, students differentiate between prime and composite numbers, a skill that lays the groundwork for more advanced topics in number theory and arithmetic.


Find the prime factors of the number 36.


The prime factors of 36 are 2, 2, 3, and 3.

Fractions and Decimals

Students in 6th grade math focus on mastering the operations of adding, subtracting, multiplying, and dividing fractions and decimals, which are crucial skills for more complex mathematics. They also learn to convert between fractions and decimals with ease, allowing for greater flexibility in solving mathematical problems.

Applying these skills to real-world contexts, students solve problems involving fractions and decimals, thereby understanding the practical applications of their mathematical knowledge.


Add the following fractions: 3/4 and 1/2.


To add fractions, find a common denominator (4 in this case) and add the numerators:

3/4 + 2/4 = 5/4.

Ratios and Proportions

Sixth-grade math introduces students to the concept of ratios, equipping them with the ability to compare different quantities and discern their relationships. They also tackle solving problems involving proportions, which is fundamental in understanding how one set of quantities is related to another.

Applying this knowledge, students learn to use ratios and proportions in various practical situations, such as adjusting ingredients in recipes when scaling them up or down, which demonstrates the real-life utility of these mathematical concepts.


If 4 students out of 20 own a bicycle, what is the ratio of students with bicycles to those without?


The ratio is 4:16 or simplified to 1:4.


In 6th grade math, students learn to calculate the area and perimeter of two-dimensional shapes such as rectangles and triangles, enhancing their geometric understanding. They also explore the properties of these shapes, focusing on angles and lines, which form the foundation for more complex geometric concepts.

Additionally, they are introduced to the concepts of volume and surface area, beginning to comprehend how to measure three-dimensional space and the extent of surfaces, skills that are essential for higher-level mathematics and practical applications.


Calculate the area of a rectangle with a length of 8 units and a width of 5 units.


The area of a rectangle is given by:

In this case,

square units

Integers and Rational Numbers

In 6th grade math, students expand their number sense by understanding positive and negative numbers and exploring the concept of integers and their place on the number line. They learn to perform operations with these integers, including addition, subtraction, multiplication, and division, which is fundamental for algebra.

Additionally, they explore rational numbers, which include fractions and decimals, and understand their position within the broader category of real numbers, laying the groundwork for more advanced mathematical studies.


Calculate the following: (−3) × 7.


(−3) × 7 = −21

Data and Statistics

In 6th grade math, students develop skills in statistics by learning to collect, organize, and interpret data, which enables them to make informed conclusions and predictions. They calculate measures of central tendency, such as the mean, median, and mode, to analyze data sets and understand their distribution.

Additionally, students create and interpret various types of graphs and charts, such as bar graphs, line graphs, and pie charts, which helps them to visually represent and communicate data effectively.


Calculate the mean (average) of the following numbers: 12, 15, 18, and 21.


The mean is calculated by adding up all the numbers and dividing by the count:

(12 + 15 + 18 + 21)/4


Algebraic Expressions

In 6th grade math, students begin to explore the basics of algebra by learning to simplify and evaluate algebraic expressions, a process that involves combining like terms and understanding the use of variables. They also tackle solving one-step equations, which is a crucial step towards mastering more complex equations in future studies.

These algebraic concepts are not just theoretical; students apply them to solve practical problems, integrating mathematics into everyday situations and preparing them for real-world applications.


Solve for in the equation .


Add 3 to both sides to isolate : . Then, divide by 2 to find : .


In 6th grade math, students are introduced to the concept of probability, which they come to understand as the measure of how likely events are to occur. They learn to calculate probabilities for simple events and experiments, using fractions, decimals, and percentages. This newfound knowledge is then applied to analyze the probability in various scenarios, including games of chance, helping students to predict outcomes and make informed decisions based on their calculations.


If you roll a fair six-sided die, what is the probability of rolling an even number (2, 4, or 6)?


There are 3 favorable outcomes (even numbers) out of 6 possible outcomes, so the probability is 3/6 or 1/2.

Coordinate Plane

In 6th grade math, students learn to plot points on a Cartesian coordinate plane, also known as the x-y plane, grasping how the x and y coordinates determine the location of a point in two-dimensional space. They understand the concept of coordinates and their role in representing precise locations on a grid.

With this understanding, they solve basic problems related to the coordinate plane, such as finding the distance between two points or identifying patterns within coordinate pairs, which is essential for their progression in geometry and algebra.


Plot the point (4, -3) on the coordinate plane.


Start at the origin (0,0), move 4 units to the right along the x-axis, and then move 3 units down along the y-axis to locate the point (4, -3).

Practical Applications

In 6th grade math, students start to apply their mathematical skills to real-life situations, enhancing their understanding of how math is used in various contexts such as finance—for budgeting and calculating interest—measurement for creating plans or models, and geometry for understanding shapes and space.

This real-world application fosters their mathematical reasoning and critical thinking, enabling them to approach and solve everyday problems with logical strategies, and preparing them for practical challenges they may encounter in their daily lives.


Calculate the total cost of purchasing 3 items, each priced at \$12.50, with a 10% discount and a 6% sales tax.


  • Find the discounted price per item: 10\% discount = 0.10 x 12.50 = \$1.25.
  • Subtract the discount from the original price: 12.50 – 1.25 = \$11.25.
  • Calculate the subtotal for 3 items: 3 x 11.25 = \$33.75.
  • Find the sales tax: 6\% tax = 0.06 x 33.75 = \$2.03.
  • Add the sales tax to the subtotal: 33.75 + 2.03 = \$35.78.
  • The total cost is \$35.78.
