There is a list of equations in which students need to categorize whether the equations have one solution, no solution or infinite solutions.
There are many ways this could be used:
I used it as a cut and paste activity where students worked together to put into the correct category. It was an easy classwork grade for me to assign, while students got to work together to think about the types of solutions.
You could pass out an equation to each student as they walked in and have them sit with people who have the same solution type.
You could post around the room and have students solve.
The possibilities are endless with this list of equations.
Please let me know how you use it. :)
