Full Notes:

Warning! I was once asked to put on a 3-day Scratch class for some public school teachers. They were so inquisitive that I had to develop lots of materials. That's why there are over 100 pages of notes here. Don't feel like you need to go through all of them.

And, BTW, I haven't yet updated all the notes to Scratch 3.0. But, you will have no trouble doing things in Scratch 3.0 from these notes.
