Thanks for your replies! I agree, don't want to change the course of the literacy teacher just for the observation. Also, this is my first observation in literacy and my mentor hasn't specified that it should be a writing lesson. Think I will stick to my guns and focus on ideas. Like the idea of spider diagram at end - could get them to draw their character and put their ideas around them, e.g. describing words, similes etc. They can look at the quality story writing (hopefully!) that results!
