Teaching mathematical vocabulary is something that can be easily overlooked. We want our students to be able to complete the math tasks at hand, but the vocabulary doesn’t always seem as important. Just like with any subject, students cannot learn what is being taught without being able to understand the language of instruction.

Before beginning any unit or chapter, preview what you are going to teach to determine the vocabulary that is essential to student’s understanding. Most math curriculums already have these vocabulary words outlined for you.

Once you have determined the words that are important for students to become familiar with, you can use the seven strategies below to introduce, model, and reinforce the mathematical vocabulary.

## Pre-Teach the Vocabulary

Consider this a preview of words. Before you begin teaching the mathematical concepts, have a day where you showcase the words. Introduce the word, its meaning, and give a brief example. By introducing the words before the skill, it is allowing students to focus on the word, not the new content being taught.

## Model

Model the vocabulary with appropriate problems. Make sure to use the vocabulary when teaching. For example, instead of asking for the answer, ask students to find the sum, difference, product, or quotient.

## In Your Own Words

After vocabulary has been introduced, have students explain the meaning of each word using their own words.

## Personal Examples

Have students provide their own examples in mathematical terms. For example if they are working with the word “factors”, have student write various number sentences where they label the factors in each of their sentences.

## Real World Scenarios

Have students list ways in which the word may be used in real world scenarios. This will help them in making valuable connections.

## Math Word Wall

We have a word wall for high frequency words, so why not a math word wall? Create a math word wall to reference periodically throughout the day/week. Give clues for a word, then students have to figure out what word you are describing. I like to call this “Being a Mind Reader”.

Math wordo, a bingo-type game, is a game we play periodically with our math vocabulary. I give students a board, or if we are short on time, I have them use a piece of notebook paper to make their own. Next, students are given a list of words to fill in their board. One word should go in each box.

Once the boards are ready, it’s game time! I read a definition to the class, and they have to find the word that belongs to the definition. Depending on your time, you can play the traditional five in a row or blackout, where all spaces must be filled to win.

They LOVE both of these!

## Use the Words in Context

I have a habit of using mathematical vocabulary throughout the day, and it is really effective. For example, when I line students up I might ask for students sitting around the “perimeter” of the room to line up first. I might also ask for students whose class number is “even” to line up first. Integrating these words throughout the day makes a HUGE difference!
