This Monster Frog Function Machine lesson plan also includes:
Elementary schoolers use a function machine in order to help them look at the relationship between input and output, and to look at the rule for the change. The machine is actually a cardboard box, and it serves quite well for the instructional activity! One student takes the input numbers and creates an output number. After enough have been done, learners try to figure out the rule that is being used. A good teaching idea!
