But that shouldn't detract from us trying to figure out how to explain the concept of a 'function' to those students who CAN get it.
How about this: function assigns a unique value to every element/ member in the domain. For example, for the domain of students: a function that assigns every student in the class their grade, another - their height, another - their age in months/weeks/days), etc.
