What's Inside

This five-page resource begins with a clear Roman numerals chart showing values from 1 to 1000. The following four pages contain 96 targeted problems divided into six distinct sections. Tasks include converting Arabic numerals to Roman and vice versa, covering numbers up to the thousands. A complete, page-by-page answer key is provided for easy grading or student self-checking.

Skill Progression

The worksheet is designed to follow a gradual-release model, building student independence.

• Guided Practice: The initial chart acts as a scaffold, allowing students to reference values as they begin. The first set of 24 problems involves direct conversions of smaller numbers.
• Supported Practice: The next sections (48 problems) increase in complexity, asking students to work with larger numbers and requiring them to combine Roman numeral symbols correctly.
• Independent Practice: The final 24 problems challenge students to convert large numbers, including years, solidifying their understanding without direct prompts, following the "I Do, We Do, You Do" instructional sequence.

Standards Alignment

This worksheet is aligned with the core concepts of CCSS.MATH.CONTENT.4.NBT.A.2, which requires students to read and write multi-digit whole numbers using various forms. While not an explicit requirement, understanding Roman numerals deepens a student's appreciation for different number systems and reinforces place value concepts. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

This resource is effective as independent practice after a direct instruction lesson on Roman numerals. It can also be used as a pre-assessment to gauge prior knowledge or as a review activity before a unit test on number systems. For a formative assessment, observe which problems students struggle with—are they having trouble with subtractive notation (like IX and IV) or with larger values? The full packet should take approximately 25 to 40 minutes to complete.

Who It's For

This worksheet is designed for 4th-grade students but can be easily adapted for advanced 3rd graders or as a review for 5th graders. It pairs well with a classroom anchor chart of Roman numerals. The clear structure makes it accessible for students who benefit from repeated, focused practice on a single mathematical skill.

This worksheet provides structured practice in converting between Arabic and Roman numerals, a skill that supports number sense development aligned with CCSS.MATH.CONTENT.4.NBT.A.2. By engaging with a non-place-value system, students gain a deeper understanding of the base-ten structure they use daily. Research from Fisher & Frey (2014) emphasizes the importance of moving students from guided to independent practice to build mastery, a principle embedded in this resource's design. The 96 problems offer the repetition needed for procedural fluency. As noted by RAND AIRS 2024, foundational number system skills are critical for later success in algebra. This resource gives teachers a reliable tool to build that foundation, providing clear evidence of a student's ability to work with and understand different numerical representations, a key component of mathematical literacy.
