I find when teaching how to write the equations of lines the best progression is as follows:
1st: Graph the function when given the equation
2nd: Match a given graph to its equation
3rd: Write the equation of function given its graph
I feel that this order helps students complete the last task better.
For this matching game, I printed the solution page of the worksheet from kuta(http://www.kutasoftware.com/freeia2.html) and cut the equation and graph on separate index cards for each group. I knew my students would find it easy and it allowed the kiddos to work with one another on a task that was not that long. I planned on using this the opener to my student's review day for their upcoming quiz but then I started to make them. To make one set took me 10 minutes and I was planning on making 10. I made 2. I plan on making the rest to use for next year-I will be making these while watching a movie or getting a student to make them! While we reviewed, I handed out the index cards to students who where done and had them match with the sets I had completed. It worked well to keep those students working with something they find 'fun'!
I also attached the notes I give my students when we first look at the writing the equation of an absolute value function graph. The lesson went well--my students typically find it "easy" and nice break.
I see it as the calm before the storm. Piecewise functions are next.
