Is there a name for this kind of book? I have one, titled "Mein Erstes Buch", that, in one small and slim volume, takes you from "Dick & Jane" and "See Spot Run" levels, to an ~3rd or 4th grade reading level, entirely in German. I picked it up because it looked neat but tried reading it one day, made it about a third of the way through, and sure enough, I could follow along. Doesn't teach you pronunciation and it doesn't replace focused practice & drilling, but it was pretty damn cool. I'd like one in French, especially, but I don't know what term to search for. "The Natural Method" from that link yields some promising results, but are there other terms?
(just checked archive.org, and sure enough, they've got a scan of the book I have, but it's a limited preview: https://archive.org/details/meinerstesbuch0000unse/mode/2up)
