To help the students remember the difference between relations and functions, we created a foldable that depicted characteristics of each. On the front we drew a Venn diagram that showed the entire oval as a relation and then inside the oval we had a circle with functions labeled. This was a two flap front so the kids could open up each flap and see the characteristics/definitions inside.
Inside we drew graphs and tables of examples and non-examples. This seemed to help the students see the similarities and differences between the two.
The students liked this one because they had visuals as well as definitions. It helped later when we reviewed for state tests because they knew what foldable to refer to if their peers got stuck answering relations vs functions questions. Not sure how I could clean it up but am open to suggestions. :)
Love your Venn diagram foldable. I adapted your idea last year in my Algebra 1 review for their EOC. I tweaked it just a bit to give it that Venn Diagram feel. I made the relation a full flap and made function a partial flap that fit inside the relation flap. It looked like a Venn diagram from the first look with the definitions and examples under the flap like yours.
ReplyDeleteI think I can picture what you did and that's a good idea as well. Much cleaner sounding. It's all in the multi-levels that I've seen you do, instead of your basic foldable. :)
