I have been working on a series called Coded Messages where students use function tables to see patterns in number and then use the completed table to find a secret message. Today's freebie is the page I have included in each book in the series that explains how function tables work.
This post explains how I got started with the series on Math Spies and you can try a free sample.

In addition I am giving away one copy of Coded Messages: Beginning Function Tables this weekend from my Teachers Notebook Store. Enter May 30-June 2, 2014.
