Advice about reading for children on key stage 2 SATS test

[TiredTA]

I've had all the training and been to all the meetings about reading for a child on the Sats tests. But I still find myself nervous about doing it wrong on the maths reasoning papers. Colleagues seem to disagree on some of the finer points of which symbols you are allowed to read. for example DFEE guidance says you cant read out mathematical symbols so obviously not + x - but what about % and £ p?
If a question said for example
Amir paid £1.50 for a pencil and 25p for a rubber what is the difference in price between the two items. Would I be able to say pound and pence?

and
Julie paid 25% less for her Jumper than Emily, how much did Julie pay? Can i say percent?

You're not meant to say either example. People probably do, and it likely rarely matters, but you shouldn't say any symbols or numbers. Just point to the written symbol or number

I heard a colleague read out the £ and p but then point to the % on another practice question, left me confused!

Not a teacher. I can see why that is the case, but it seems a shame.

My DD is having a reader for her maths GCSE resit due to dyslexia / processing speed (not sure exactly what issue got her which concession). She can process better when she hears alongside seeing the text.

Y6 teacher here. Using your examples, I would say 'Amir paid this much (pointing) for a pencil and this much (pointing) for a rubber. What is the difference in price?'
'Julie paid this much (pointing) less for her jumper than Emily...'

To be honest if you are reading those signs the student is unlikely to get the answers without knowledge.

If you can't read a % sign you are very unlikely to be able to calculate the difference.

You shouldn't read out either.

Definitely can't read the percentage. I'm not convinced £ is a mathematical symbol though. It is used in pretty much all extended formal writing, for example in a newspaper, in a way that x or % would not be (it would say times/multiply and per cent in words). In the same vein, I wouldn't consider cm to be a mathematical symbol - like p for pence it's an abbreviation.
