My dd has become a free reader today and I'm so pleased for her. She stopped at level 13 and we've agreed she will read books from home. The only thing is I have no idea of their reading level. Is there a national database or similar which gives reading levels for kids books? The first book she's chosen is Aristotle by Dick King-Smith but I'm worried the teacher will find this a bit too young? Next she wants to read the Daisy and the Trouble with Life series, and she may go for her entire Mr Men Collection! Are they suitable at all?
