I am posting this free "Interactive Whiteboard" lesson. I used it when I taught Algebra 1 a few years ago at a school that has a SMART Board (or similar brand). I can make no promises as to the accuracy of this product, nor can I tell you particular details on the lesson, as I don't remember, and I no longer have the application that it was created on. I can tell you that I used it with Saxon Algebra 1, lesson 78 (older edition). If you find inaccuracies or anything out of place, please fix these errors and re-post the file as a free item.
