So much of math teaching is actually language teaching as well. There are quite a few math vocabulary words kids must understand in order to learn math concepts. It’s like a whole other language! That’s where these free printable math vocabulary lists and cards come in handy.
There are two lists: one for grades K-3 and one for grades 4-6. Each set of words is organized by concept strand and then alphabetized for easy use. There will be some overlap and you may find, depending on your class, that you will use words from both lists.
The printable cards are great for creating a word wall and for a variety of learning activities. As you introduce a concept, consider adding each new vocabulary word to the word wall. In fact, some teachers like to add pictures or examples to the word wall. You could do this or invite students to take turns helping to “manage” and “enhance” the word wall. Then use the cards for some of the activities below to engage and excite students about learning the “language of math.”

Activities Using the Math Word List and Cards
What Is It?
Give each student a white board or a piece of paper and something to write with. As you introduce a word, for example “square,” hold up the vocabulary card and ask, “What is this? Can you draw it or write an example?” You can use almost any words, such as addition equation, two-digit number, quadrilateral, sum, and so on.
Some words might require more words, numbers, and/or drawings. Make sure students understand by doing a couple of examples. After you ask the question and show the word card, take a walk around to look at and have students share their responses.
Math Word Concentration
Using index cards, write a vocabulary word on one and on another an example or picture. On the back of each pair, write the same number. Make at least 10 pairs depending on the concept you are working on.
Mix the cards up and put them face down on a table or floor with a dividing line between words on one side and examples on the other (a piece of yarn works well here). Have students take turns flipping two cards over trying to find a match of word card and example card. You can play as individuals or teams.
It’s a lot of fun and a great learning experience to have students make their own card sets to share with the class.
Math Clue Cards
Using the cards created for Concentration (see above), choose a word card and describe or give clues to the targeted word. For example, for the word “square,” you might say, “It has four sides, all four sides are straight, all four sides are of equal length.” Demonstrate this a few times, and then let students take turns picking cards and supplying clues.
Can You Use It in a Sentence?
Using the Concentration cards again, put the cards in a stack, face down. Have a student turn over the top card and use the word in a sentence that demonstrates understanding. For example, let’s say a student picks the word “Add.” An acceptable sentence that shows understanding could be, “When I add 2 + 2, I get a sum of 4.” An unacceptable answer, one that doesn’t show understanding, would be, “I like to add.” Give these as examples so everyone understands the criteria for a good answer.
You can play this as a class, small group, or partners.
Math Word Bingo
Prepare bingo cards or sheets with the math vocabulary words you want students to practice. For younger students, a bingo card with eight spaces is a good start. For older students, the card can have up to 25 spaces (with a “Free Space” in the center).
There are a few ways to play. You could start by having a helper student pick a card from a pile and read it out loud. Players mark that square with whatever token you’d like to use. Once they have a row or column filled in, they call out, “Math Bingo!”
Another way to play is to call out a definition or example and have players hunt for the math vocabulary word that matches the example. You could also reverse that by preparing cards with examples and having helpers call out the vocabulary words. There are lots of ways to have fun with this game!
