File for the Post: Relations and Functions Card Sort This lesson was created for a mandatory tutorial session for Algebra 1 students. I was in charge of creating a 30 minute review lesson over "Relations and Functions." This lesson had to include a 5-10 minute review lesson and an activity. First, students went over this graphic organizer with four practice problems to review relations and functions. After students reviewed relations and functions, they independently completed the following cut and paste activity. If you read my blog, then you know all about my love for card sorts! Students had to match up the correct table, graph, map, and ordered pairs together and determine if the relation was a function. If you download the activity, then you will notice that there is a separate document that does not require cutting (if you do not have the time). Sorry for the short and sweet post, I just had several teachers ask for the cut and pasted document.
