This activity has students graphing linear functions. When finished, their graphs will have created a picture (a diamond)! They will need to know how to graph lines with fractional sloped and non-fractional slopes. They will also need to know how to graph vertical and horizontal slopes. There are only 3 linear functions like this, and since my students did not know how to do this, I decided to walk them through this part as the example. A fun way to engage the kids!
