Do you need to make it a 'lesson' and plan it? We have a 30 minute library slot each week where the whole class go. I chose different children to scan the books in and out, others to tidy the shelves - eventually every child would have done both. The rest choose a new book and quietly read while waiting. We read a story or some poems together and then go back to class. Does it need to be planned further than this? Am I short changing my class? lol.
