Yes, my daugter does that too - flipping from easy picture books to more advanced chapter books and non-fiction. HOwever, at school I notice she selects the easiest books - I will talk to her as to why. She also came home from school yesterday saying 'I was the last one to finish my maths worksheet and I had to be told to stop talking 3 times'. Apparently, the teacher had to help her finish it as she was taking so long.... tHis is very easy maths - she passed this level plus more in the WIAT achievement at 4.5 and does maths on her brother's maths program at home - which easiest level is about 2 to 3 years ahead of this school work. Go figure?
