Math teachers know that the domain is all the X-values and the range is all the Y-values of a function, a set of coordinates, or a graph. However, some students will have difficulty understanding these concepts. A domain and range activity to complement your next lesson will strengthen your student’s understanding and offer you real-time student data on their progress. Read on for a list of ten engaging activities to enhance your unit on domain and range!
1. Relation Match Up
Provide your algebra students with the relation R = {(1,2), (2,2), (3,3), (4,3)}. Then, provide them with a t-chart where the domain is on the left and the range is on the right. Print out the numbers 1, 2, 3, 4 (domain) and then 2 and 3 for the range. Instruct students to match the numbers to their appropriate columns.

2. Trigonometric Matching
Provide your students with this student answer sheet, but cut the values for the domain range columns out. Pair students up to see who can complete the domain cards the fastest. There won’t be any more difficulty with the domain of trig functions after this activity!

3. Linear Function Match
Enhance learners’ understanding of the domain with this simple activity. Print out a few linear functions, such as the one pictured here, but remove the function so that all it shows is a line. Give cutouts of the written function as a practice to students so they can match the function with the line.

4. Linear Function Table
Here’s another simple domain and range match activity. Give students the linear function table you see here and have them graph the points. See if they can use the information provided to write out the linear function. Once complete, have them come up with more f(x) matches for the domain.

5. Highlight Match Up
Another awesome domain and range-matching activity using highlighters! All you need is a worksheet with a few graphs, and students can color in the correct domain.

6. Make a Machine
Some students will have difficulty understanding that the domain moves left and right while the range moves up and down. To solidify this knowledge, have them create a discrete domain and range machine to visualize the concept. It’s no Jean Adams domain activity, but it will do!

7. Play Kahoot
Use this fourteen-question, digital activity to shake things up. Who can find the domain and range match to the right answer the fastest? Visit Kahoot.it to get acquainted with the full version of the game before introducing it to your learners.

8. Domain Cards Quizlet
I really like this well-thought-out flashcard list domain and range match-up. These flashcards allow teachers to list domains and range sorting as well as match, print, and digital. It is entirely up to you! Launch a game of Quizlet Live to add some competition to your next lesson.

9. Get Moving
Each student has a list domain and range card that belongs to one function that has been graphed out and hung on a wall. The point of the game is to have students get up, look around the room, and figure out which graph matches their list domain.

10. Memory Game
Take your basic childhood memory game to the next level by turning it into a list-domain-and-range match-up! Half the cards will list a domain and range, while the other half contains the function associated with that domain and range. A match is made when the correct domain and range are flipped in the same turn as its corresponding function.
