# Activities to Teach Students to Evaluate Functions

As a math teacher, one of the most essential skills to impart upon your students is how to evaluate functions accurately. Evaluating functions is a vital concept of algebra that is the basis for understanding higher math levels, including calculus. While many students initially find functions to be daunting, there are several creative activities you can use to help teach students how to evaluate functions and make it a fun and engaging experience.

1. Puzzle it out:

One of the most engaging ways to teach students to evaluate functions is to create puzzle worksheets that require them to match the functions with their inputs and outputs. You can even mix and match different levels of difficulty to ensure that all students can participate and engage with the material. As students work through the puzzles, they will begin to develop an intuition for how to evaluate functions, making it easier for them to solve more complex problems later on.

2. Real-world problems:

There’s no better way to engage students than by showing them how the math they are learning can be applicable in real life. Create problems based on real-world problems that require them to evaluate functions. For example, you can provide a situation where a restaurant is calculating the number of customers they expect based on the number of reservations or the numbers of staff on hand. This engages the students and enables them to relate their math work with things happening around them.

3. Online games:

Using online games platforms such as Kahoot or Quizlet can also help engage and teach students how to evaluate functions. You can create fun quizzes that require students to match input and output values or order of operations for evaluating functions. This helps them to revise what they have learnt and to come up with strategies for solving problems faster.

4. Graphing:

Another tool for teaching students how to evaluate functions is graphing. By plotting the graph of a particular function, students can understand the function’s behavior and create a picture that will help them better understand the problem at hand. You can use graphing calculators or online tools to enable students to visualize the graph and use it to identify key points or determine maximum or minimum values.

5. Group work:

Collaborative work can be an engaging way of teaching students to evaluate functions. You can assign projects and activities that involve students working in groups and utilizing each other’s strengths. This encourages cooperation and helps students get a different perspective of the material. You can also encourage student-led techniques to solving problems that will help their peers understand better.

In conclusion, teaching students to evaluate functions is an essential part of algebra that lays the groundwork for higher math levels, including calculus. By using engaging and creative activities, including puzzles, real-world problems, online games, graphing, and group work, teachers can help students better understand and apply the concepts of evaluating functions. These tools will motivate students to learn and remember the material, equipping them with a solid foundation for succeeding in math and beyond.
