Function Machine
http://www.shodor.org/interactivate/activities/fm/index.html
Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs.

Function Machine
http://www.amblesideprimary.com/ambleweb/mentalmaths/functionmachines.html
This online tool has you put in a number, and then it spits out a result. Your goal is to determine what the function machine is doing to the number. You can choose the type of function it uses or let it be random.     

Mystery Functions
http://www.northcanton.sparcc.org/%7Etechnology/excel/files/mystery_functions.html
This is an Excel spreadsheet activity for the whole class or individual student use. There are 20 different mystery formulas in this spreadsheet. For each one the student enters several numbers for the "Input" and examines what comes out for the "Result", trying to determine each function by looking for patterns.

Number Cruncher
http://www.shodor.org/interactivate/activities/numbercruncher/index.html
Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule on without at least having two data points.
