I've co-taught classes on Scratch and Python (seperate classes) to kids from 8 to 13. One recommendation is https://www.nostarch.com/ https://www.nostarch.com/ - No Starch Press. There are a number of good titles in the kids section. They were also very decent in giving us a classroom discount for materials. We used ChromeBooks as that is what the school had for kids. It is OK for Scratch but less than desirable for Python. We used repl.io for an IDE and it wasn't bad. It is better to use IDLE if possible... I've had an idea of teaching a class where the beginning part is to get a Rasp Pi up and running - 1 per kid or 1 per pair. After that use the Raspberry Pi to learn Python / Scratch.
