Complete Evaluating Decimals Worksheet | Grade 6 Math

Mastering Decimal Operations

This worksheet provides targeted practice for Grade 6 students on evaluating numerical expressions involving decimals. Through a structured set of problems, learners will apply the correct order of operations (PEMDAS) to build fluency and accuracy with multi-step calculations, a foundational skill for success in middle school mathematics and pre-algebra concepts.

At a Glance

• Grade: 6 · Subject: Math
• Standard: CCSS.MATH.CONTENT.6.EE.A.2 — Evaluate expressions and perform arithmetic operations in the conventional order.
• Skill Focus: Evaluating decimal expressions (Order of Operations)
• Format: 5 pages · 40 problems · Answer key included · PDF
• Best For: Independent practice, skill reinforcement, or homework
• Time: 25–40 minutes

What's Inside

This resource includes a comprehensive five-page worksheet set designed for thorough practice. Each of the five sheets contains eight unique problems, for a total of 40 questions focused on evaluating expressions with decimals. A complete, corresponding five-page answer key is provided for easy grading or student self-checking, showing the final answer for every problem.

Skill Progression

The worksheet set follows a gradual-release model to build student confidence and independence:

• Guided Practice: The first sheet (8 problems) establishes the core process of applying PEMDAS. Use it with teacher support or as a warm-up.
• Supported Practice: Sheets two and three (16 problems) increase complexity slightly, ideal for pair work with access to anchor charts.
• Independent Practice: The final two sheets (16 problems) serve as an independent assessment or homework, allowing students to demonstrate mastery.

This "I Do, We Do, You Do" structure ensures all learners progress toward proficiency.

Standards Alignment

This worksheet directly aligns with Common Core standard CCSS.MATH.CONTENT.6.EE.A.2, which requires students to evaluate expressions using the standard order of operations. It also reinforces the Grade 5 standard for decimal computation (CCSS.MATH.CONTENT.5.NBT.B.7). Both codes can be copied directly into lesson plans or curriculum maps.

How to Use It

This set is ideal for use after a direct instruction lesson on order of operations with decimals. Use the sheets for guided practice, independent work, or as a multi-day homework packet. For formative assessment, observe how students handle expressions with parentheses versus those without to spot misconceptions. A single sheet takes about 10-15 minutes.

Who It's For

This resource is designed for 6th-grade math students but also works as a review for 7th graders or an extension for advanced 5th graders. To support learners, provide a PEMDAS anchor chart or a calculator for checking work. Pair this worksheet with a lesson on financial literacy to connect the skill to a practical context.

This worksheet packet provides focused practice on a critical pre-algebra skill aligned to CCSS.MATH.CONTENT.6.EE.A.2: evaluating numerical expressions using the standard order of operations. Proficiency in this area is a key predictor of future success in algebra. Research consistently shows that procedural fluency, built through structured practice, is essential for freeing up cognitive space to tackle more complex problem-solving. A major analysis by the RAND Corporation (RAND AIRS 2024) reaffirmed the importance of foundational skills practice in middle grades mathematics to ensure students are prepared for higher-level thinking. By offering 40 distinct problems across five sheets, this resource gives students the repetition needed to internalize the PEMDAS process with decimals, enabling them to approach multi-step calculations with confidence and accuracy and preparing them for algebraic manipulation.
