This is a set of 30 relations, one per 8-1/2 by 11 sheet of paper/cardstock. Some of the relations are functions; some are not. The relations come in 4 formats: graphs (both discrete and continuous), tables, mappings, and sets of ordered pairs.
I use these cards in multiple ways to ask the students if each relation is a function or not and what is it's domain and/or range. You could post them around the room; you could hand one to each student. I have stood at the door, one card at a time and asked each student one at a time whether the relation I was showing them was a function or not. If they got it right, they could come in. If they didn't, then they went to the end of the line and tried again. I did this every day until everyone was getting them right. I've put the students in groups and given them one of each to decide if they were functions or not. You could give each student one card and have them group themselves on the side of the room based upon whether their card was a function or not. They could be used as a sorting activity. The usefulness of these cards is limited only by your imagination. Laminate for longer use. 30 pages total.
