Use these pages for keeping record of your students input and output function machines. I have the students make function machines out of cartons and then make 15 cards to go in them. They have to decide what the input will be, what the function will be, and what the output will be based on the function (or the rule). The second page is for them to use when they trade and answer another students function machine questions.
I used small note cards for the actual cards they put into the function
