Algebra 1 - functions

This is the part where we started examining functions. The unit lesson had us talking about the special relationship (linear) between two variables using Ticket Prices. We did a four corner model where we wrote the question and identified the variables in the upper left corner, drew our table in the upper right corner, graphed in the bottom left corner, then did a verbal summation in the bottom right corner. In the middle, we wrote the title, function rule and the type of function or main idea for the lesson. The kids liked doing our function study this way and it helps the kids with seeing the different representations. I did this same thing for the relations page, but didn't use the four corners. This lesson was the first time i utilized the four corners. Thr four corners model was something I wanted to continue for the rest of the year but didn't due to the transfer issue. I cannot stress how helpful a document camera is for journaling. If I had a SMARTboard or other interactive board, I might sing their praises. As it is, I have a projector, a regular whiteboard and a recently purchased document camera. I'll go into technology later, but y'all need to know I am not provided the latest and greatest technology due to small district size.

So here it is, the four corners representation model. You can modify as you wish. Some have suggested writing domain and range with the graph instead of with the summary. I think you should do what fits your teaching style and what helps the kids remember.
