Activities to Teach Students the Composition of Linear and Quadratic Functions: Find an Equation

As students begin to learn about linear and quadratic functions, it’s important to provide them with engaging and effective ways to learn about the compositions of these types of functions. Here are several activities that you can utilize in your classroom to help your students better understand the composition of linear and quadratic functions and how to find their equations.
1. Group Work
Divide your class into groups of two or three students each. Provide each group with a set of linear or quadratic functions on index cards. Have the groups work together to find the composition of the functions and then write out the equation for the resulting function. To make the activity more challenging, you can ask the students to swap their cards with another group to see if they can still solve the composition.
2. Puzzle Matching
Create puzzle pieces with linear or quadratic functions on them that are cut in half. The students are then tasked to match the correct halves of the puzzle pieces together to create the correct composition of the function. You can also provide a set of completed puzzles and have the students work backward to determine the individual functions that make up the composition.
3. Graphing
Provide the class with a set of linear and quadratic functions on graph paper. Ask the students to graph each function and then find the composition between different functions. Finally, have them graph the resulting function to understand how the two functions interacted.
4. Real-World Application
Provide the students with a real-world scenario that can be represented as a linear or quadratic function. Ask students to find the composition of this scenario as it relates to a certain function. This will help them see the practical application of functions and how they can be used to solve everyday problems.
Overall, teaching the composition of linear and quadratic functions requires creativity and engaging activities that can help students understand the concepts. The above activities provide a great foundation for students to work with and can be easily adapted to suit different classroom needs. By providing these activities, you will help your students to better understand how functions work and how to find their equations.
