Monday Math Freebie - Function Machine Fun

I've been trying to find a fun way to practice basic facts while working with patterns and function machines. I think this idea works well.  Player 1 draws a Function/Rule card and hands his/her partner the number cards that correspond to the input numbers. Player 2 selects one of the input numbers and places it on the inbox of the function machine mat. Player 1 reads the rule on the Function/Rule card and places the correct output number on the outbox of the function machine mat. Player 2 records the information on an Input-Output Chart and tries to determine the rule. Play continues in this fashion until the rule is determined or the player runs out of recording spaces. After each player has taken four turns guessing the rule, players total their scores (total number of guesses needs) and the lowest score wins.

Here are a few sample images.

I hope you get a chance to use this in your home or classroom. Please let me know if you try it and how it works!
