My dd is in reception. at the present time she is on level 2 ORT books. The system in dd class is that they must read every book at each level, to move on. They change the books 2x a week. The books she brings home she is finding quite easy. So i did a little experiment today and bought a level 4 ORT book. She did ok, needed a little help. My question is why do they have to read every book in each level, what is the educational theory behind it. I have no problem with the level she is on as we do lots of reading at home. Im just wanting to understand the process of learning to read and why so many schools vary in their approach to reading.
