To preface this, I'm not at all worried, just curious after seeing so many 'writing levelling' posts on here 
This is my DS1's first "essay", his homework was to buy something by himself, counting out the money etc, then write about his experience:
" I went to the shopping centere. I went to STARBUCkS. I Bought a juice. It cost £1.50. I had £1.40 so I asked for ten pens. My mummy gave me ten pens so I could Buy my juice. the End."
