# Setting the Table for Functions: A Video Collage

Functions are not difficult, but sometimes educators can gloss over the most important step: their introduction. Functions are everywhere... a food processing plant, the soda machine, a phone bill, even natural selection. So many times teachers jump right into the numbers that they do not take enough time to explain their purpose and create analogies that can link math concepts to their own world. These resources will give a firm introduction to the input-output machine; the function.

Setting the Table for Functions: A Video Collage
• ## Introduction to Functions - Part 1

12:03 Minute Video
Mark Weimer says:
After reinforcing the idea of a what a function is, this video jumps into working through mathematical functions. There are many videos that do this, but this one does so in a very clear, complete manner. In this video, functions are superbly introduced from which it progresses into domains and ranges.
• ## Introduction to Functions - Part 2

10:03 Minute Video
Mark Weimer says:
This video is part 2 of a 2 part video and has all the strengths of part 1. It is precise, clear, and focuses on domains, range, and graphing.

## The Algebra Toolbox

Mark Weimer says:
There are fun ways to teach and then there are the rest of the ways. If you can get the class actively involved, students will retain more of the information. This blog is a great resource if you are looking for activities to do inside the classroom. Many students find it hard to engage with math, but how many math teachers have students running around the classroom and signing songs.
• ## What is a function?

7:56 Minute Video
Mark Weimer says:
An excellent starting point from the Khan Academy that, in addition to this video, also offers an entire series of videos and exercises to guide students through the mastery of linear functions. The video itself offers a fewer more complex functions as examples and as is the case with most videos from the Khan Academy, it is concise, informative, and can of course be paused and replayed repeatedly.
• ## Graphing a Basic Function

5:36 Minute Video
Mark Weimer says:
It can be hard to write an infinite number of solutions on a test page. That is a lot of paper. Luckily, math has some helpful tools like graphs on which infinite solutions can be illustrated. This is a great walk-through from Sal Khan on how to graph a function.

This blog is great and it's author understands the importance of an analogy. Functions are machines, factories, algorithms... whatever you want to call them. But calling them something of this sort is a very important first step for students. This math teacher's blog give you some season advice for a tough unit.
