This week, for that reason, we went through the letters which he remembers on call. Seems about half of them without a prompt and the vast majority with the prompt.
The surprising thing is in many cases he would struggle with the most common and, as I thought , familiar to him letters, yet write without hesitation letters that he's barely written, like both 'W' 'w' s
Still. I think he'll soon get around remembering how to write all of them as per need. I suspect that the difference in sounds and letters is still bit of a problem. For example, we agree that he writes 'a' and he writes 'r'! Could it be my accent when asking, lol. Anyhow. We working on it.
We are also working on writing words as per sound. For example I ask him to write 'mum' , 'dad' 'cat' and so on, simple words. O was struggling with the whole concept, quite a bit, but even by the end of the first lesson, it got a bit better for him. Expecting, this is going to be a slow one. Not surprised though , writing words on hearing is HUGE! With the way English phonics work, I feel for him already, I really do!!!
