Where they differed most
You presented these facts to the school governors: reading scores up 12% since the new library scheme; £3,000 needed to extend it to Years 3 and 4; volunteer readers doubled to 22. Now write what you would SAY to a Year 6 assembly about the same scheme (max 100 words) — same truth, their language, and one concrete thing you are asking the children themselves to do.
Year 6, our new library reading scheme is making a real difference: reading scores have risen by 12%. More people are getting involved too—our volunteer readers have doubled to 22. We want Years 3 and 4 to benefit as well, but extending the scheme will cost £3,000. You can help right now: choose a book you love, write a short recommendation for it, and add it to our “Year 6 Must-Reads” display. Your suggestions could inspire younger pupils to discover great books and become confident readers too.
Good morning, Year 6! Since our new library scheme began, reading scores have risen by 12%, and the number of volunteer readers has doubled to 22. Now we want Years 3 and 4 to enjoy it too, but extending the scheme will cost £3,000. You can help without spending any money: this week, choose one book you love and write a recommendation card for a Year 3 or 4 pupil. Your choice could help someone discover their new favourite book!
