That fed into a game where I said the name of a book in the boys library collection & he told me if it was Fiction or Non-Fiction. To my surprise he got it right every time! We played it so many times that I couldn't think of any more books. Phew!
So, today, he made Fiction & Non-Fiction labels.
Showed his Montessori credentials by insisting that he check that the widths of his labels matched ;)
Laid out 2 mats...
Collected a pile of books from his room..
& got sorting :)
