What's Inside

This four-page PDF contains three pages of student exercises and a complete answer key. It features 124 problems across 12 sections (A-L). Tasks progress from basic computation to multi-step word problems with unit conversions, ensuring a thorough review of decimal operations.

Skill Progression

The worksheet uses a gradual release model to move students toward independence.

• Guided practice: Initial sections focus on multiplying and dividing decimals by powers of 10 to reinforce place value.
• Supported practice: Middle sections transition to more complex calculations involving whole numbers and other decimals.
• Independent practice: Final sections feature challenging word problems requiring students to apply their skills in context, solidifying their understanding.

This structure helps all learners build mastery.

Standards Alignment

This worksheet directly aligns with CCSS.MATH.CONTENT.6.NS.B.3, requiring students to fluently compute with multi-digit decimals. It is also an excellent review for 7th graders working with rational numbers (CCSS.MATH.CONTENT.7.NS.A.2). The standard codes can be copied into lesson plans.

How to Use It

This worksheet takes about 40-55 minutes. It's ideal for independent practice after a lesson, as homework, or as a review packet. Use it for formative assessment by observing where students struggle to identify specific skill gaps that need reteaching.

Who It's For

Designed for 6th and 7th-grade math students, the clear progression helps learners needing structured practice while challenging advanced students. Pair with a place value anchor chart to support students struggling with decimal point movement.

Procedural fluency in decimal operations is critical for middle school math and future algebra success. This worksheet aligns with CCSS.MATH.CONTENT.6.NS.B.3, where students fluently multiply and divide decimals. Research from RAND AIRS (2024) notes that automaticity with rational number arithmetic is a key predictor of readiness for higher-level math. Its 124 problems provide the deliberate practice needed for procedural skill. By mixing computation with word problems, this resource helps students develop the 'how' and 'when' of using decimals, a core principle for lasting mathematical understanding.
