ELL Scaffolds for Elementary Math: Vocabulary, Sentence Frames, and Task Supports

Math is often described as a universal language — but the language of math instruction is anything but universal. Word problems, mathematical discourse, and the academic vocabulary of elementary mathematics present significant language barriers for ELL students. The concepts are often accessible. The language that surrounds them is not. This page covers how to make elementary math accessible to English learners without reducing the mathematical rigor.

The Language Demands of Elementary Math

Elementary math instruction is far more language-dependent than most teachers recognize. Students are expected to read word problems, explain their reasoning, describe patterns, compare quantities, and discuss strategies — all in academic English.

The specific language challenges:

Word problems combine math concepts with dense syntactic structures — parsing a complex conditional sentence before any math can happen
Mathematical vocabulary includes everyday words used in technical ways — table, plot, round, change, difference, product — that ELL students may know in their everyday sense but not their mathematical sense
Explaining reasoning requires academic oral and written language that ELL students are simultaneously acquiring

Sentence Frames for Elementary Math

Understanding the problem

The problem is asking me to ___.
I need to find ___.
The important information is ___.
I can use ___ (addition / subtraction / multiplication / division) because ___.

Showing work and reasoning

First I ___. Then I ___. Finally I ___.
I know ___, so I ___.
I used ___ strategy because ___.
My answer is ___. I know this is reasonable because ___.

Comparing and patterns

___ is greater than ___ because ___.
___ is less than ___ because ___.
A pattern I notice is ___.
This is similar to ___ because ___.

Explaining to a partner

I solved this by ___.
A different way to solve this is ___.
I agree with ___ because ___.
I got a different answer because ___.

Task Supports for Elementary Math

Visual representations for word problems. Before students attempt a word problem, have them draw what is happening. A simple sketch removes the language barrier between the problem and the math.

Word banks for written explanations. When asking students to explain their reasoning in writing, provide the key math vocabulary they will need: because, first, then, equal, total, difference, strategy.

Sentence frames inside math journals. Every written explanation prompt gets a frame. "I solved this problem by ___. My answer is ___ because ___."

Manipulatives with vocabulary labels. When using base ten blocks, fraction tiles, or geometric shapes, label the manipulatives with the vocabulary students are expected to use.

Partially worked examples. Show the first step of a multi-step problem, then ask students to complete the remaining steps. Reduces the language demand of understanding what to do without reducing the mathematical thinking required.
