NLVM Function Machine

My virtual manipulative this week is in Number Operations Grades 9-12. It is the Functon Machine and focuses largely on pattern recognition. The manipulative has a few numbers (1 through 4) that are entered into the function machine. The machine spits out an answer and the exercise it geared to recognize a pattern formed in the input inserted into the machine. The exercise closes by having the user make educated guesses on what the next values of outpit would be based on the attern recognized in the first 4 input values (1 through 4).
