Are you following the renewed framework for Literacy? Do your children write independently or copy the words on cards. The next stage of their writing would be to use their phonic knowledge to write words and sentences. This is just an example and I am trying to help blindly but you could do some work on a story with a familiar setting e.g school the characters are just them selves e.g I lost my teddy. I was very sad. I looked in ...... I found it ..... I was very happy. A simple story but children can use own knowledge to write these sentences. Look at talk for writing - but the next stage for writing would definately be independence and getting the children to apply what they know. Obviously teaching them by modelling the writing - capital letter full stops what sounds can i hear ? How do i write the letter that makes that sound. Another place to look for ideas would be developing early writing i think you can still get it from the national strategies website. PM me if you would like any help .
