I want to have my students do a graphing project - something where they will do 10 lines, tell me the line equations, and color it.
I want to introduce domain and range - but have always had trouble with this in the classes I teach.
Yesterday, I got a brilliant idea. I will give them the option of doing lines without any domain limitations (imagine 10 lines drawn on a graph, then colored like a stained glass). Then I will show them another (imagine a simple house) where I discuss domain (but not range) and the line equations.
They can do either. And they will be allowed to work in groups.
We'll see.
