The ability to write a cheque (or check) seems to have been flushed down the toilet along with being able to spell, write by hand and walk to the bank. So here's what you need to do with that bright new cheque book.
Firstly you'll need a pen... remember pens? No, that's a pencil and can be rubbed out. Yes that's a pen... no it's not broken, you just have to press the top and the nib comes out... very good! Let's start with the easy part: the date. Mmm... you don't spell February like that... no the universe does not come with a psychic spell checker. Yes, I know, June and July are short and easy. OK, now who are you going to write the cheque to? That's nice but "my mum" is not really her name... what's her name? Just "mum", OK, perhaps you can ask her one day. Erm... that big space there is to write out the number in words so let's not run before you can walk, let's put a number in that big box there. This is just an exercise, so any number will do... except a zillion... and there is no way you're going to have a googol in the bank either. Yes, they're funny... marginally. OK, that looks likely, now for the PhD level part of this: writing that number out in words! Yes, words! .......... (!!!) ......... One thing, you also need to practise your signature. Good... and this one... and this one... you're good at this bit, aren't you! OK, that's wonderful, let me keep this for you until the next cheque writing lesson. Right, here's a bit of plastic, don't chew it or try to open locked doors with it.
If you really need help with writing a cheque (or check) then this might help.
