I use this book every year for the school year with toddlers ... Ideal for labeling in place ... In the book: Behind each door hides the content (as it is a door of various closets of the house) We work on vocabulary: other doors, other hiding places ... Then it adjusts the gates of the school ... What's he hiding behind? We visit the building ... and I always leave a door behind which one has to guess ... Drawings questions ... And I do the same with the sports center ... Book j'adooooore !!
