There’s a lot or reasons to teach math vocabulary in a math class. In another post, I compiled a list of my favorite justifications for doing so, plus several tips to make it happen. Below are five free resources for teaching math vocabulary in the middle school math classroom.

## Math Word Wall Cards

### 1. Ratios and Proportions

This resource has color-coded word wall cards for terms like *percent*, *ratio*, and *unit* *rate*.

### 2. Fractions

Bring fractions to life with these easy-to-use word wall cards. Nuts-and-bolts terms like *denominator*, *numerator*, *reciprocal,* and *whole number* are illustrated and defined.

## Interactive Notebooks

These interactive notebooks focus on vocabulary. The concepts can be explored in tandem, on the facing page.

### 3. Coordinate Plane

The foundation of so much middle school math is built. This INB is a good way to preview, review, teach, or re-teach the coordinate plane, its function, and related terms.

### 4. Operations

This interactive math notebook includes pre-filled-in and blank printable templates, along with concise, kid-friendly definitions and step by step instructions for building the foldables.

## Crosswords

### 5. Geometry Vocabulary Crosswords

Wha? Crosswords in a math class? Perfect for when you have a sub who is a bit rusty in the maths. I also use ’em in homework packets, and for early finisher work. I assign them more than once a school year, too! The kids have yet to notice!

# About math vocabulary, a wise person once said…

Sometimes, when explaining math vocabulary to my class, I feel like a dog chasing its own tail. Perhaps that’s why the mathematician Henri Poincare was fond of saying, “Mathematics is the art of giving the same name to different things.” A few other great minds had deep insights into the language of math.

The power of mathematics is often to change one thing into another, to change geometry into language. – *Marcus du Sautoy*

Pure mathematics is, in its way, the poetry of logical ideas. – *Albert Einstein*

Mathematics is the music of reason. – *James Joseph Sylvester*

A person whose mind has gone astray should study mathematics. – *Francis Bacon*

## Is zero a number, or what?

I thought I knew until I read Math Lingo vs. Plain English by Reuben Hersh.
