Thinking back to reading as a child myself, I can’t remember the ‘scheme’ I was following exactly or any of the stories I read, but what I can remember is the excitement of choosing a new book and even more so, the feeling of utter elation when moving up to ‘the next colour’. I clearly remember what a good day it was when that coloured sticker changed (particularly if it was metallic!) and I’m sure that children still feel the same way now. It’s obvious – it’s a milestone reached, a reward for trying hard, a sense of achievement and an exciting challenge to be reading harder books.
