Math = Love: Function or Not a Function Card Sort

Function or Not a Function Card Sort

Today I'm sharing a new card sort I made for my students to practicing classifying a relation as a function or not a function. My old card sort for this was stolen from someone else and resized on the copy machine, so I didn't have a digital copy. Last week, I decided to create a new one instead of trying to track down my paper copy of the old one I had been using.

Here's what I came up with:

I tried to include as many different relations as possible in as organized a way as possible to reduce cutting time. Students don't have to think about how to cut around each relation. They just have to cut on the dotted lines.

And, as a bonus, you only need to print one sheet per three students!

I decided to print them on blue paper.


Some of my students did their sorting in their notebooks. 





Others did their sorting on their desk then glued the results in their notebooks afterwards. 


Either way, I did enforce that students get their sorting checked BEFORE gluing them in their notebooks!

  4. I was looking at the OpenMiddle problem you have on creating 3 functions and 3 non-functions. It looks like they cut out the numbers to fill them in for the chart, but how many sets of numbers do they need? Is it 6? It looks like an awesome activity, but I'm looking for more explanation on it please.
