There really aren’t many resources for Scala that don’t assume previous programming knowledge. I have been teaching Scala for CS1 and CS2 since 2010, and I had to create my own material to do it. That material is available as textbooks (“Introduction to Programming and Problem Solving Using Scala” and “Object-Orientation, Abstraction, and Data Structures Using Scala”) and videos on YouTube (https://www.youtube.com/channel/UCEvjiWkK2BoIH819T-buioQ). For an organized view that associates playlist with chapters you can go to http://www.programmingusingscala.net/. The CS1 book and videos truly assume that you have never programmed before. The CS2 materials ideally build off the CS1 stuff, but they also include an introduction to Scala for anyone with programming basics coming from a different language.
I think that “Atomic Scala” was also aimed at the complete beginner, but I don’t know when it was last updated. The second edition of my books just came out in the last year and all the code was written for and checked with Scala 2.12.
