Does the order of numbers matter when you add or multiply? It might seem like a simple question, but understanding this core concept – the commutative property – is a fundamental building block in a child’s mathematical journey. As teachers and parents, we constantly seek effective ways to explain and reinforce these ideas. That’s why we’re thrilled to offer a fantastic resource: 9 free Commutative Property Worksheets, complete with answer keys in PDF format, designed to make learning (and teaching!) this principle a breeze.
These aren’t just any worksheets; they are a comprehensive set designed to solidify understanding of the commutative property for both addition and multiplication. Let’s dive in!
What Exactly is the Commutative Property?
Simply put, the commutative property states that changing the order of numbers in an addition or multiplication equation does not change the sum or product. Think of it as numbers being flexible dance partners – they can switch places without changing the final dance move!
Commutative Property of Addition:
This rule says that if you have two numbers, say ‘a’ and ‘b’, then a+b=b+a. For example, 3+5=8, and 5+3=8. The order doesn’t affect the outcome. This is a crucial concept for early learners, helping them see patterns and simplify calculations.
Commutative Property of Multiplication:
Similarly, for multiplication, a×b=b×a. For instance, 4×2=8, and 2×4=8. Again, the result remains the same regardless of the order. This understanding is vital as students move towards more complex multiplication problems and algebra.
It’s important to note that the commutative property does not apply to subtraction or division. For example, 5−2=3, but 2−5=−3. The order very much matters in these operations!
Why Practice with Commutative Property Worksheets?
Understanding the theory is one thing, but practice is where the magic happens. Our commutative property worksheets offer several benefits:
- Reinforce Understanding: Repeated exposure to varied problems helps students internalize the concept.
- Build Confidence: Completing the worksheets boosts a child’s confidence in their math abilities.
- Develop Number Sense: Working with these problems helps students become more familiar with number relationships and how operations work.
- Prepare for Advanced Topics: A solid grasp of basic properties like commutativity is essential for tackling more complex mathematical concepts later on, including algebra.
- Identify Learning Gaps: For teachers and parents, these worksheets can help pinpoint areas where a student might be struggling.

Here’s a breakdown of what you’ll find:
1. Commutative Property of Addition Worksheets (60 Problems Total)
These worksheets focus exclusively on how the order of addends doesn’t change the sum. They are progressively challenging to cater to different learning stages.
Worksheet 1: Single-Digit Wonders (20 Problems) Students will work with basic single-digit additions, like 2+7=7+_ or finding the missing number in $ _ + 6 = 6 + 9$. This is perfect for 1st-grade students or those just starting with the concept.
Worksheet 2: Double-Digit Adventures (Numbers 10-40) (20 Problems) Here, we step it up with two-digit numbers between 10 and 40. For example, students might solve 12+25=25+_ or 31+_=18+31.
Worksheet 3: Expanding Horizons (Numbers 10-100) (20 Problems) This worksheet broadens the scope to include two-digit numbers up to 100, offering more complex practice, ideal for a 2nd-grade and 3rd-grade commutative property of addition reinforcement. Think problems like 47+88=_+47.
2. Commutative Property of Multiplication Worksheets (60 Problems Total)
These worksheets are tailored to help students understand that the order of factors does not affect the product.
Worksheet 1: Single-Digit Foundations (20 Problems) Focusing on basic multiplication facts using single digits. For example, 3×8=8×_ or identifying the missing factor in $ _ \times 5 = 5 \times 7$. Great for students beginning their multiplication journey, often in 3rd grade.
Worksheet 2: Multiplying with Teens and Twenties (Numbers 10-40) (20 Problems) Students will practice with problems involving factors between 10 and 40, such as 15×4=4×_ or 22×_=11×22.
Worksheet 3: Mastering Double Digits (Numbers 10-100) (20 Problems) This advanced multiplication worksheet uses factors up to 100, ensuring a thorough grasp of the commutative property with larger numbers. Example: 50×23=_×50.
3. Mixed Commutative Property Worksheets (Addition & Multiplication) (60 Problems Total)
To ensure students can differentiate and apply the property correctly across operations, these worksheets combine both addition and multiplication problems.
Worksheet 1: Single-Digit Mix-Up (20 Problems): A blend of single-digit addition and multiplication problems where students must apply the correct commutative rule. For instance, 6+4=4+_ alongside 9×3=3×_.
Worksheet 2: Double-Digit Blend (Numbers 10-40) (20 Problems) This worksheet mixes problems like 17+32=32+_ and 20×5=5×_, using numbers between 10 and 40.
Worksheet 3: Comprehensive Challenge (Numbers 10-100) (20 Problems) The ultimate test of their understanding, this worksheet features a mix of addition and multiplication problems with numbers up to 100.
Making the Most of Your Commutative Property Worksheets
These free printable commutative property worksheets are versatile tools. Here are a few tips for teachers and parents:
- Start with Explanation: Before handing out a worksheet, briefly review the commutative property with clear examples related to addition and multiplication.
- Guided Practice: Work through a couple of problems together to ensure students understand the task.
- Independent Work: Allow students to complete the worksheets at their own pace.
- Check with the Answer Key: Use the provided answer keys to review their work. This is a great opportunity to discuss any mistakes and reinforce the concept.

Beyond the Worksheet: Fun Ways to Teach the Commutative Property
While worksheets are excellent for practice, you can also reinforce the commutative property through other engaging methods:
- Use Manipulatives: Use blocks or counters to physically demonstrate that, for example, 3 blocks + 2 blocks is the same quantity as 2 blocks + 3 blocks.
- Real-Life Examples: Point out commutative situations in daily life. “Does it matter if we put the apples or the oranges in the bag first? The total fruit is the same!”
- Create Posters: Have students create colorful posters explaining the commutative property of addition and multiplication with their examples.
