Addition and subtraction with Roman Numerals

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Encourage students to talk through their thinking as they work: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These addition and subtraction with roman numerals worksheets work well as daily practice, homework, or a focused review activity.

These addition and subtraction with roman numerals worksheets for 3rd grade give students the structured, hands-on practice they need to build confidence and fluency. Students work through a range of problem formats, from visual models and diagrams to written equations and word problems, so they encounter addition and subtraction with roman numerals from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 3rd grade. Practicing addition and subtraction with roman numerals at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

This worksheet is designed for 3rd Grade students (Ages 8-9), aligned to Common Core standard 3.NBT.A.2. It can also be used as review for early students at the next grade level or as an introduction for advanced students.

Yes. This worksheet works for homeschool, classroom, and tutoring settings. Print individual pages for targeted practice, or print the full set as a packet. Works great as a morning warm-up, independent center activity, or fast-finisher task.

Third graders are typically introduced to Roman numerals I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000) and the rules for combining them: additive (VII = 7) and subtractive (IV = 4, IX = 9, XL = 40, XC = 90). While not a core CCSS standard, Roman numeral knowledge appears in many curricula and enriches number system understanding.

Start with the seven base symbols and their values, then teach the additive rule (smaller or equal symbols to the right are added), and the subtractive rule (a smaller symbol to the left means subtract). Limit practice to numbers under 100 initially. Worksheets that ask students to convert between Arabic and Roman numerals provide structured practice.

Roman numerals appear in real-world contexts: clock faces, book chapters, movie titles, building dates, and sporting event numbering (Super Bowl LVIII). Learning them deepens number system understanding by showing that different cultures developed different numeral systems. It also reinforces place value appreciation by contrast - Roman numerals have no zero and no positional value.
