Fiddle with a Function Machine

The Function Machine game builds mental math skills and has always been a favorite of my math club students. Now you can play it at home:

Choose your type of rule, if you wish — or for the best challenge, click the Random button. Then type a number in the machine and click Activate. The machine will give you back an answer.

Try several numbers. Can you figure out what the machine is doing?

When you are pretty sure of the answer, click the arrow to reveal the machine’s program. Were you right?
