See my first post on linear functions here. This is what the rest of the unit looked like:
Above was supposed to be a matching game, but the students didn't enjoy it very well. I was frustrated, but maybe we should have played bingo like @mpershan (see his post it's trig bingo). Anyway here is my template. (To view file open in google docs and download original in word.) I had each student graph 6 equations before starting, and then pair up with someone who had six different equations and play memory.
Then we wrote linear equations. Kids practiced a few and then came up with their own. It is hard to figure out how to think about something that is happening over and over again, so it was a struggle. Also I feel this is something that is very difficult to differentiate for and provide interventions for....
That was the end of our unit on linear functions. We moved onto exponential functions!
