A data investigation looking at different elements of books. Pupils have to investigate average number of letters per word and average number of words per sentence. You could choose different book extracts if you prefer, google is a good place to get those. You could just do one of the investigations instead of both. There's a few ideas for analysing the data, so you could take out what you don't need for your class and just do the ones they can already do. You could include a guide on how to do the things they don't know, or need to revise how to do. Adaptable for lots of ideas.
