Add and subtract 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 add and subtract roman numerals worksheets work well as daily practice, homework, or a focused review activity.

These add and subtract roman numerals worksheets for 4th 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 add and subtract roman numerals from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 4th grade. Practicing add and subtract roman numerals at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

"Add and subtract Roman numerals" is written for 4th Grade (Ages 9-10), and it covers Common Core 4.NBT.A.2. If your little one is a year younger but already steady on roman numerals, the page still works. You may just need to read the instructions out loud. And if they are older and add and subtract roman numerals never quite stuck, this is a short review rather than busywork.

Yes, both. We made it for 4th Grade roman numerals, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with add and subtract roman numerals. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

The most reliable method is to convert both Roman numeral operands to Arabic numbers, perform the arithmetic, then convert the result back to Roman numeral form.

Students must perform two conversions (in and out) around an arithmetic operation, which tests Roman numeral fluency, number sense, and multi-step thinking simultaneously.

After mastering reading and writing, operations-level practice ensures students can work flexibly with Roman numerals rather than just recognize them passively.
