This is my favorite lesson I've ever created :) After learning about function machines and number patterns, students get to "operate on function machine patients to save them"!
I let my students wear scrubs, doctors masks, and gloves so they could really pretend to be doctors during this activity. They worked in groups to operate on each "patient". The patients have function machines as their bodies. The "Rule" for the machine goes in the heart--so we talked about how the rule is the MOST important part of the machine, because it makes it work. Students cut out and glued the correct missing input and output numbers, and added the rule into the heart. They loved it!
This download contains 16 different function machine "patients". Each patient sheet has a problem solving walkthrough at the top, where students must answer each step to work towards finding the rule.
