If you had not heard, then radio 2 are currently in the middle of their annual 500 words competition for under 13 year olds.
My (almost 9) year old has aspirations of entering, but unfortunately lacks the motivation to actually write anything down.
He made an absolutely brilliant start, with a lot of prompting and suggesting from me, asking the right questions and setting up triggers for him to generate his own answers.
He is rather better at drawing than writing – maybe all he needs is a picture . . . . after all then he would have 1000 words worth . . . .
