The Boy in the Striped Pyjamas - Chapter 1
Since you have been studying WW2, I thought this book would be very topical - plus it's a great read (one of my favourites). I read this as a whole class read with the year 6 class 2 years ago and they absolutely loved it, so I hope you do too. I will include some work on the holocaust for your topic work next week, to help give you more background on the history.
I hope you enjoy chapter 1.
