From the site:
“These resources are meant for teachers and parents who want to have their children fall in love with computers and see the magic of programming.
I’m staying away from philosophical debates of whether kids should learn to program, when they should start and other such topics. I know this — I fell in love with computers in 3rd grade (a beautiful ZX Spectrum), and I want to share the joy of programming with others.
I’ve chosen in this list to be quite comprehensive in listing all resources — but also choosy to restricting this to things I found useful & of high quality.”
