Some people become confused when rounding as it seems to them that it does not link to their existing knowledge but to those people I say 'You're a stinky potato!' You see, we all use the skills of rounding regularly. For example, I was in a park recently and needed to put my empty marshmallow packet into the bin so...what did I do? I looked to see if there were any bins near me and I spotted three? What did I then do? Of course...I decided which was nearest and went to it. I wasn't going to waste my energy going to a bin that was not the nearest!
