My dd has just been moved from S7 of ORT on to New Way Readers. She loves the stories and far prefers them to Biff et al. However the vocabulary is far less challenging. I'm not particularly bothered about this, as I know that her teacher will simply move her on until she is at the right level.
However even looking at the charts published on previous links, I can't find any reference to green specifically or work out the hierarchy of colours in this series. Does anyone know where this might be?
