Help please with phonics letters and sounds.

[Harleyisme]

Any helpful advice would be great.
I am currently temporarily homeschooling sen ds till ehcp sorted and a suitable school found.

So in school they learn the students phonics so its done on sounds rather than letters. We are having to relearn year one spellings with ds as we had a 3 week break for summer holidays and in this time he has forgotten. A lot of year one spelling words are none decordeable. He is trying to spell by using phonics sounds which is all good apart from he doesn't seen to be registering the letters that make the sounds for example spelling were he will say or w then ere i then ask him to either find the letters or make them out of playdough he looks at me blankly. So he gets that phonic sounds make up words but seems to not associate the sounds with letters. Hopefully that will make sense and someone will have a idea on best steps forward. I am wondering of i need to go back to basics on the alphabet.

@ChazsBrilliantAttitude thank you i will take a look that actually makes sense.

Have a look at handwriting families, as well. If he practices the letter formation in isolation, he'll get better at consistently going anti-clockwise for a, c,d,g,o,q and maybe s. The letters all begin the same way, which is helpful.
Then there's b,h,k,m,n,p,r

Handwriting is really useful, not for aesthetics but for letter recognition.
