How to Support ELL Students in Math: 7 Strategies

Supporting English language learners in math means treating language development and mathematical thinking as two goals you pursue at the same time, not separately. The good news is that math already offers built-in tools for this: visual models, patterns, symbols, and hands-on objects that let students reason through problems even while their English is still developing. The key is pairing those tools with deliberate language support so students can both understand instruction and communicate their thinking.

Keep the Math Challenging While Adding Support

A common instinct is to simplify the math for students who are still learning English. That approach backfires. Students fall behind in content while gaining little language benefit from easier problems. WIDA, the organization behind the English language development standards used across most U.S. states, promotes a “scaffolding up” approach: maintain grade-level mathematical rigor and layer in the support students need to access it.

In practice, this means planning two things for every lesson. First, identify where the mathematical challenge lives, whether that’s a new concept, a multi-step problem, or abstract notation. Second, build in specific supports (visuals, collaborative tasks, sentence frames, vocabulary previews) that help students engage with that challenge rather than avoid it. The goal is independence over time. You’re not permanently lowering the bar; you’re building a ramp to the same bar.

Use Visual and Concrete Representations

Visual representations are one of the most powerful tools you have because they let students demonstrate mathematical reasoning without relying heavily on English. The concrete-representational-abstract (CRA) framework gives you a clear progression to follow.

  • Manipulatives: Physical objects like base-ten blocks, fraction tiles, or algebra tiles let students build and touch the math. These work especially well when introducing new concepts because students can explore relationships before they have the English to describe them.
  • Number lines: Useful across grade levels for addition, subtraction, fractions, and integers. The goal is for students to eventually internalize a mental number line, but the physical version gives ELL students a way to show their thinking visually while building that internal model.
  • Pictorial representations: Simple drawings like circles for ones and lines for tens help students understand place value and operations. These bridge the gap between physical objects and abstract symbols.
  • Strip diagrams: Rectangles drawn to show relationships among quantities. These are especially helpful for word problems in upper elementary and middle school, where the language load is heaviest. A strip diagram lets a student map the structure of a problem visually before solving it numerically.

When you model a visual representation, talk through your reasoning out loud. Explain why you chose that particular representation for that particular problem. This think-aloud process teaches students not just the math but the decision-making behind it, and it exposes them to the academic language they’ll need to use themselves.

Teach Math Vocabulary Explicitly

Math has its own specialized vocabulary, and much of it trips up ELL students in ways that aren’t obvious. Words like “table,” “product,” “expression,” “plane,” and “volume” have everyday English meanings that conflict with their mathematical definitions. Other terms like “denominator” or “coefficient” have no everyday equivalent at all. Both categories need direct instruction.

A few approaches that work well together:

  • Word walls with visuals: Post key vocabulary for each unit where students can see it during class. Include a simple definition, a visual or diagram, and an example. Refer to the wall regularly during instruction so it becomes a living resource, not decoration.
  • Personal glossaries: Have students keep a math vocabulary section in their notebooks. When you introduce a new term, students write it, sketch a visual, and use it in a sentence. The act of producing the word in context helps it stick.
  • Preview before the lesson: Spend two to three minutes at the start of a lesson introducing the key terms students will encounter. Use visuals and gestures. This small investment pays off because students aren’t hitting unfamiliar words mid-problem when their cognitive load is already high.

Use Sentence Frames for Mathematical Discussion

One of the biggest barriers ELL students face in math isn’t computation. It’s explaining their reasoning, justifying answers, and participating in class discussions. Sentence frames solve this by giving students a language structure so they can focus on the mathematical content.

A sentence frame looks like this: “I know that ______ because ______.” Or for comparing: “Both ______ and ______ have ______, but they are different because ______.” The frame handles the grammar and academic phrasing while the student fills in the math.

To create effective frames, write out a model response to the question you plan to ask. Look at the sentence structures in your response, then strip out the content-specific parts and replace them with blanks. Create frames at different levels of complexity. A student in early stages of English proficiency might use “The answer is ______ because I ______,” while a more advanced student might use “I can justify my solution by showing that ______.” Post frames on the board during the lesson and provide printed copies students can keep in their binders. As students grow more comfortable with the language patterns, gradually reduce frame use.

Design Collaborative Math Tasks

Pair and group work gives ELL students low-pressure opportunities to practice mathematical language with peers. But unstructured group work often leads to ELL students staying silent while English-proficient partners do the talking. Structure matters.

Assign specific roles that require every student to contribute. One student might be the “recorder” who writes the group’s solution, another the “explainer” who presents the reasoning, and another the “questioner” who asks clarifying questions. Rotate roles regularly so ELL students practice all forms of participation. Provide sentence frames for each role: the questioner might use “Can you explain how you got ______?” and the explainer might use “First I ______, then I ______.”

Think-pair-share is another reliable structure. Pose a problem, give students individual thinking time (critical for ELL students who may need to process in two languages), then have them discuss with a partner before sharing with the class. The partner conversation serves as a rehearsal, letting ELL students try out their ideas and language in a safer setting before speaking to the whole group.

Connect Math to Students’ Experiences

Abstract math becomes more accessible when it connects to something concrete and familiar. This is true for all students, but it’s especially important for ELL students whose background knowledge and cultural experiences are assets you can draw on. When teaching percentages, use contexts like shopping discounts or recipe adjustments. When teaching measurement, connect to cooking, building, or sports that students know.

These connections also create natural opportunities for language production. A student who might struggle to explain an abstract fraction problem can talk fluently about splitting a pizza or dividing supplies among friends. Start with the familiar context, build the mathematical concept on top of it, then gradually move toward more abstract representations.

Plan for Language at Every Stage of the Lesson

Effective support for ELL students isn’t a single strategy bolted onto a lesson. It’s woven into every phase. Before instruction, preview vocabulary and activate background knowledge. During instruction, use visuals, think-alouds, and gestures alongside verbal explanations. When students practice, provide sentence frames and collaborative structures. When students demonstrate understanding, offer multiple ways to show it: diagrams, equations, verbal explanations, or a combination.

Pay attention to word problems especially. They pack the heaviest language demands in math class. Before students solve a word problem, read it together and identify the mathematical action hiding inside the language. Words like “altogether,” “remaining,” “each,” and “shared equally” signal specific operations, but only if students know what those words mean. A quick annotation step where students underline key words and sketch what’s happening in the problem can make the difference between a student who’s stuck on the English and a student who’s doing the math.

Monitor and adjust your scaffolds over time. The WIDA framework describes six levels of English proficiency, and students at different levels need different amounts of support. A student who needed heavy visual scaffolding in September may be ready for more independent work with sentence starters by January. The point of scaffolding is to remove it as students build proficiency, so check in regularly and pull back support when students show they’re ready.
