Error Analysis Function or Not a Function
On our first day we will review the definition of functions. Before we delve into the details of the definition, students will visit posters of graphs on the walls with a partner and determine if the graph represents a function or not. After experiencing the math for themselves, we will spell out the specifics of the definition as we check the work.
To make sure students understand the definition I have an "error analysis" exercise for them. The error analysis exercise is a one-page worksheet (8 problems) that already has answers. Some answers are correct, some are incorrect. Students need to rework the page, identify the incorrect solutions, and explain the error in thinking. Here is a link to the activity. If you modify it, share your changes so I can learn from you!
