Function machines

We've been looking at function machines. You put a number in at one end, something is done to  the number, and, usually, a different number comes out at the other end. It wasn't quite like that the first time we tried it though,,,

We had a few more goes using our expensive and sophisticated Year 4 function machine:
Then we tried it out in pairs, making up our own functions:
Tomorrow we'll try some more two-step funtions, and maybe use this online function machine too:
