# Common Core Math Explained: 8 Common Core Math Examples To Use In The Classroom

Common Core math examples can be a tricky world to navigate for teachers trying to meet the individual needs of their students. Having a bank of Common Core math examples to hand can be helpful when planning your lessons.

Embraced by the majority of states in the U.S., the Common Core math standards help to develop students’ conceptual understanding, problem-solving skills, and real-world applications.

In this article, we explore what Common Core math is, 8 Common Core math examples and top tips for educators teaching Common Core math.

### What is Common Core math?

Common Core math standards are a set of educational standards for mathematics adopted by forty states in the United States. Each standard outlines the math knowledge students should know and be able to do at each grade level, from kindergarten through to high school.

These standards aim to provide a more focused and coherent set of learning goals for students, emphasizing conceptual understanding, problem-solving, and critical thinking skills.

Often, Common Core math involves multiple strategies and approaches to solving problems. In turn, this encourages students to understand the underlying concepts rather than simply memorizing algorithms.

One aim of the Common Core State Standards is to move away from traditional memorization of procedures and algorithms towards a deeper understanding of connections between mathematical concepts.

Common Core math standards are organized by grade level and cover a wide range of mathematical topics, including:

• Arithmetic
• Algebra
• Geometry
• Statistics
• Probability

Each standard is divided into domains, which represent broad categories of mathematical content such as:

• Counting and cardinality
• Operations and algebraic thinking
• Numbers and operations in base ten
• Measurement and data
• Geometry

3rd to 6th grade Common Core math test

Common Core math standards have been controversial in some areas due to concerns about curriculum changes, standardized testing, and complexity. But some argue that these standards provide a more coherent approach to mathematics education and better prepare students for higher education than traditional math.

### How is Common Core math different from traditional math?

Common Core math and traditional math represent two different approaches to teaching mathematics.

Traditional math typically refers to methods of teaching mathematics that were used before the adoption of the Common Core standards. These methods often focused on rote memorization of formulas and procedures, with less emphasis on understanding the concepts or on real-life application of mathematical skills.

Here are some key differences between the two:

#### Focus on conceptual understanding vs. memorization

A strong emphasis is placed on developing students’ conceptual understanding of math concepts under the common core. It aims to help learners understand the “why” behind mathematical procedures rather than just memorizing algorithms.

Traditional math often focuses more on rote memorization of formulas and procedures without necessarily understanding the underlying concepts needed to approach math questions.

#### Problem-solving and critical thinking vs. rote practice

Common Core math problems encourage critical thinking skills. They promote multiple approaches to solving new math problems and require students to justify their reasoning.

Often, traditional math involves repetitive practice of standard procedures with less emphasis on problem-solving and critical thinking.

#### Real-world applications vs. abstract exercises

Connections between mathematical concepts to real-world situations is valued under the common core. This helps students see the relevance of the math skills they are learning. Tasks and problems require the application of mathematical skills in practical contexts.

Traditional math lessons focus more on abstract exercises and textbook problems that may not always have clear real-world connections.

#### Depth of understanding vs. breadth of coverage

Rather than covering a wide range of topics, Common Core math aims for depth of understanding and maths mastery. Fewer topics at each grade level allow for deeper exploration and mastery of key concepts.

In contrast, traditional math tends to cover a broader range of topics in less depth.

#### Flexibility and multiple strategies vs. one correct method

Students are encouraged to use multiple strategies and approaches to solve problems through the Common Core math standards. Flexibility and creativity are valued when approaching problem-solving.

Emphasis on a single “correct” method or algorithm for solving problems is the general approach in traditional math. Overall, Common Core State Standards aim to develop students’ mathematical proficiency in alignment with the demands of the modern world. This includes the need for critical thinking, problem-solving, and application of mathematical concepts to real-world situations

### 1. Make sense of problems and persevere in solving them

Students should not only be able to understand problems and make sense of them, but persevere in finding solutions.

Finding solutions may involve math skills such as:

• Analyzing problems
• Making conjectures
• Planning approaches to solving math problems

#### Common Core math example 1

A student is faced with a word problem about finding the area of a garden. They must take the time to carefully read and understand the problem before attempting to solve it.

This problem may require several approaches to answer the math question. Small group work and discussion can encourage students to persevere through the challenge and try different strategies until they find a solution.

### 2. Reason abstractly and quantitatively

In order to reason abstractly, students need to be able to make sense of quantities and their relationships in mathematical situations.

This will be easier for students if they can take abstract information from context and quantify information. Being able to decontextualize and contextualize mathematical ideas will benefit students.

#### Common Core math example 2

A graph shows the relationship between the number of hours worked and the amount earned. Students can analyze the graph to determine patterns and make predictions about future earnings based on proportional relationships between hours worked and money earned.

For example, if John worked for 13 hours, how much money would he earn?

### 3. Construct viable arguments and critique the reasoning of others

Introducing math vocabulary in the classroom helps students construct viable arguments and critique the mathematical reasoning of others. Exposure to mathematics language and sentence stems will help students to reason mathematically, construct arguments, and justify their thinking, without creating cognitive overload.

#### Common Core math example 3

During a class discussion about strategies for solving a particular math problem, you might ask students to present their solutions — justifying and explaining their reasoning.

They can also be encouraged to critique each other’s approaches, identify strengths and weaknesses in their arguments and offer alternative methods.

### 4. Model mathematics

Math lessons should prepare students to use math to solve real-world problems. It may help students to do this if you represent mathematical concepts with visual models and math manipulatives

#### Common Core math example 4

Subtraction of fractions is a skill that many students struggle with. Using a visual model to describe and analyze the word problem can release cognitive load for students.

For example, Paul had 11 ⅔ yards of twine. He used 6 ½ yards to make macrame wall hangings, how many yards of twine does Paul have left?

### 5. Use appropriate tools strategically

To solve math problems effectively and efficiently, students must be able to select and use appropriate tools. This includes recognizing when and how to use tools, as well as evaluating effectiveness and efficiency.

#### Common Core math example 5

When solving a complex geometry problem, students should recognise the effectiveness of using a protractor and ruler to accurately measure angles and lengths.

For example, Given an angle ABC where point B is the vertex of the angle, construct an angle bisector of angle ABC using a ruler and a protractor. Then, using the angle bisector you have constructed, draw a line segment from point B to the bisected angle’s line that is exactly 5 cm long. Measure and report the angle sizes of the two new angles created by the angle bisector.

### 6. Attend to precision

Calculations need to be carried out precisely. To do this, students need to be aware of key mathematical terminology for the Common Core Standards they are studying. This involves using appropriate units and labels and stating mathematical results clearly.

#### Common Core math example 6

A student ensures that their work is clear and organized. They pay attention to detail, avoiding errors and inaccuracies in their calculations. Below is a worked example of a student showing how to solve a word problem involving multiple percentages.

### 7. Look for and make use of structure

Solving math problems accurately means students need to recognize and use mathematical patterns and structure. They should be able to identify relationships between mathematical ideas and make connections between different mathematical representations.

#### Common Core math example 7

When solving a multiplication of decimals problem, a student recognizes that breaking down the whole numbers and decimal parts into their factors makes the problem easier to solve. They identify the underlying structure of the problem and use it to their advantage.

### 8. Look for and express regularity in repeated reasoning

Identifying and generalizing patterns and regularities in mathematical situations is key to proficiency in problem soving and reasoning. Students should be able to notice repeated reasoning and use it to solve math problems efficiently.

#### Common Core math example 8

Example: A student identifies similarities between a problem they’re working on and a previous math problem. They utilize the patterns in the prior example to complete the new problem. This also helps them to solve similar problems in the future.
