Session 3: Functions and Algorithms

In Session 1, we looked at patterns in pictures, charts, and graphs to determine how different quantities are related. In Session 2, we used patterns and variables to describe relationships in tables and in situations like toothpicks and triangles. This session extends the exploration of relationships to include the concepts of algorithm and function.

Homework

In this session, we will explore algorithms and functions. We will:
•	Understand the importance of doing and undoing in mathematics
•	Determine when a process can or cannot be undone
•	Use function machines to picture and undo algorithms
•	Understand that functions produce unique outputs


	Throughout the session you will be prompted to view short video segments. In addition to these excerpts, you may choose to watch the full-length video of this session.
