Commutative Associative And Distributive Properties Worksheet

Commutative Associative And Distributive Properties Worksheet

Understanding the fundamental properties of mathematics is essential for building a strong foundation in algebra and arithmetic. Among these properties, the commutative, associative, and distributive properties play crucial roles in simplifying expressions, solving equations, and manipulating mathematical operations. In this article, we provide a comprehensive worksheet focusing on these key properties, designed to reinforce students’ understanding and mastery of algebraic concepts.

Worksheet: Commutative, Associative, and Distributive Properties

Instructions: For each question, apply the appropriate property (commutative, associative, or distributive) to simplify the expression.

1. Commutative Property of Addition:
Example: 3 + 5 = 5 + ___
Answer: 3 + 5 = 5 + 3 = 8

2. Commutative Property of Multiplication:
Example: 4 × 7 = ___ × 4
Answer: 4 × 7 = 7 × 4 = 28

3. Associative Property of Addition:
Example: (2 + 3) + 4 = 2 + (___ + 4)
Answer: (2 + 3) + 4 = 2 + (3 + 4) = 2 + 7 = 9

4. Associative Property of Multiplication:
Example: (5 × 6) × 2 = 5 × (___ × 2)
Answer: (5 × 6) × 2 = 5 × (6 × 2) = 5 × 12 = 60

5. Distributive Property:
Example: 3(4 + 2) = ___ + ___
Answer: 3(4 + 2) = (3 × 4) + (3 × 2) = 12 + 6 = 18

6. Simplifying Expressions:
Example: 2(3x + 4y) = ___ + ___
Answer: 2(3x + 4y) = (2 × 3x) + (2 × 4y) = 6x + 8y

7. Applying Multiple Properties:
Example: (6 + 2) × 5 = ___ + ___
Answer: (6 + 2) × 5 = (2 + 6) × 5 (Commutative Property of Addition) = 8 × 5 (Associative Property of Multiplication) = 40

8. Advanced Application:
Example: 4(3x + 2y) + 2(5x – y) = ___ + ___
Answer: 4(3x + 2y) + 2(5x – y) = (4 × 3x) + (4 × 2y) + (2 × 5x) + (2 × -y)
= 12x + 8y + 10x – 2y
= 22x + 6y

This worksheet provides students with opportunities to practice applying the commutative, associative, and distributive properties in various algebraic expressions. By mastering these fundamental properties, students can simplify expressions, manipulate equations, and solve problems more effectively. Regular practice with worksheets like this can enhance students’ understanding of algebraic concepts and improve their problem-solving skills. As students progress through the worksheet, they gain confidence in their ability to apply mathematical properties and tackle more complex algebraic tasks.
