ALEX Lesson Plans
Subject: Mathematics (9 - 12)
Title: Building Functions: Composition of Functions
Description: This lesson provides a review of evaluating functions and finding function rules as well as an introduction to the composition of functions. The review is accomplished through the use of an online exploration using a function machine. The idea of a function machine is also used to explain the composition of functions. Instruction is provided in finding the composition using several different representations of functions (input/output tables, graphs, and function rules).  This lesson results from the ALEX Resource Gap Project.

Subject: Mathematics (9 - 12)
Title: It's All in the Family
Description: Students will be motivated to learn how to build new linear functions from existing linear functions.  Students will bring pictures of themselves and their parents from home to personally involve them in the lesson.  Students will learn to use the patterns inherent in functions to quickly and accurately graph linear functions.  This lesson will only deal with vertical shifts and the steepness of the line.  Horizontal shifts will be dealt with in future lessons. In addtion, in future lessons  students will transfer this knowledge to also graph exponential, quadratic, and absolute value functions. This is a College- and Career-Ready Standards showcase lesson plan.
