To reduce the confusion of what blocks are under what folder as well as provide a document the teacher, volunteers and students can use to find information, I created a word document that is organized by folder.
The intention is to provide structure and reduce student frustration in
finding blocks and what blocks the folders contain.
Hope this helps. Let me know if this is of help to others.
All our blocks have reference documentation (right click on any block and select Help from the menu). We also have a dynamically-generated Blocks Gallery page for all our editors.
