What's Inside

This five-page file includes a four-page worksheet and a complete answer key. The worksheet has seven sections covering divisibility rules, identifying factors, prime vs. composite numbers, prime factorization, GCF, LCM, and word problems. The clear layout guides students through the concepts systematically.

Skill Progression

The worksheet follows a clear gradual-release model.

• Guided practice: It begins with foundational skills like divisibility rules and identifying factors, with 8 problems for each concept.
• Supported practice: Students then move to prime factorization and finding the GCF and LCM of number pairs, with 4-6 problems per section for focused practice.
• Independent practice: The packet ends with four word problems requiring students to apply their understanding of GCF and LCM to scenarios.

This structure ensures all learners can access the material.

Standards Alignment

This worksheet is aligned with CCSS.MATH.CONTENT.6.NS.B.4, which requires students to find the greatest common factor and least common multiple of whole numbers. The exercises provide extensive practice in this core number system standard. The standard code can be copied directly into lesson plans.

How to Use It

Use this resource after direct instruction on GCF/LCM. Assign it as in-class practice, a partner activity, or as homework. For formative assessment, observe which section is most challenging; for example, issues with prime factorization signal a need for review. Most students will complete the packet in 40-55 minutes.

Who It's For

This is for 6th-grade math students but serves as an excellent review for 7th and 8th graders needing to solidify number sense before algebra. For students needing support, pair this with a divisibility rules anchor chart. The final word problems challenge advanced learners.

This worksheet provides practice for CCSS.MATH.CONTENT.6.NS.B.4, a critical standard for number sense. Fluency with factors and multiples predicts algebra success. Research shows procedural fluency and conceptual understanding must be developed in tandem; this resource supports both by moving from procedure to application. According to the RAND AIRS 2024 report, worksheets with high-volume, structured practice on a core skill are effective for reinforcement. By offering 40 problems across seven tasks, this packet gives students the repetition needed to build automaticity in their mathematical reasoning before tackling more complex algebraic concepts.
