Activities to Teach Students to Match Exponential Functions and Graphs

Exponential functions are important for students to learn as they have many real-world applications. Matching exponential functions and their corresponding graphs is an essential skill that students need to develop. In this article, we will discuss some activities that teachers can use to help their students learn how to match exponential functions and graphs.

1. Use Real-Life Examples

Start by introducing your students to real-life examples of exponential functions. Some examples include population growth, interest on savings accounts, and radioactivity decay. Encourage them to make observations about how these phenomena change over time and how they can be represented mathematically. After introducing these examples, present corresponding graphs and ask your students to match them correctly.

2. Create a Matching Game

Create a game to help your students practice matching exponential functions and their corresponding graphs. To create the game, print out several graphs and equations on cards, shuffle them, and have your students pair them up correctly. You can also make it a competition for bonus points or prizes to make it more engaging for the students.

3. Use Desmos

Desmos is a free online graphing calculator that enables students to create and graph exponential functions. Have students create exponential functions and graphs, then compare them to already created ones, and challenge them to match them. Desmos also offers pre-made exponential function activities, which can be assigned to the students, so you don’t have to create your own if you prefer.

4. Create a Gallery Walk

Make a classroom gallery walk by hanging several graphs and functions around the room. Ask your students to walk around and match the functions with their corresponding graphs. This activity can be turned into a mini-competition where students work in small teams to solve the questions and get the most matches correct.

5. Play Mathematical Bingo

Bingo is a fun and engaging way for students to practice matching exponential functions and graphs. To create a bingo card, print out several graphs and equations, and fill in bingo boxes with their respective graph/images. Each student gets a Bingo card, and the game begins. The teacher or another student can call out a graph or function, and the students can cover the corresponding box if they have it in their card.

Matching exponential functions and graphs is an essential skill that students will use throughout their mathematical journey. These activities will help your students learn this skill while also having a lot of fun. By providing engaging activities, you can make math lessons exciting and enjoyable for your students.
