If so, please would you give me some advice.
DS1 started reception in September. He's at a small, quite academic, private school, with another 9 children in his class. He loves it and has settled in very quickly and made friends.
He brings a reading book (Oxford Learning Tree most basic level) home every night, and I have been given the 100 high frequency words on flashcards. He recognises I, me, my, he, look, can, see, all, we, went, her, at, is and a few more words.
He has been memorising the sentences in the books, and he doesn't recognise each of the words that he has memorised, so teh teacher has asked that we do more woprk on flashcards at home, rather than the reading book (I am still reading 3 or 4 other books to him every night - he loves books and always has). The teacher tells me that they do not teach phonics at school, and when I asked how I teach him new words on the high frequency word flashcards, she told me that I should let him guess, and if he doesn't know the word, to give him the first letter of the word only, and not sound the word out.
So that is what I have been doing. But DS1 doesn't retain the words at all. So eg we can be looking at 'was' and he will guess that it is 'we' or 'when' or whatever (sometimes he will guess any wprd at all, even if it doesn't begin with w), and I will say no, and say that it begins with 'w' and he won't know what it is, so I will say that it is 'was'. But he won't remember that, and we go through the same process on different occasions and different days and he just doesn't retain that the word is 'was'.
So, my question is, how do I try and help him understand these new words? I have been trying to make short sentences using a few of the words to make it more fun eg "I can see them" when I know that he knows "I" "can" and "see", but it isn't making much of an impression.
