I used floflo for the current book we’re reading and I think a lot of other people did too, it was really helpful, so is we (or you) ever read a book that’s on there, it’s definitely worth seeing whether you can at least pre-learn some vocab for it.
Yeah, the vocab list is good. It’s being filled out as we read. So if you encounter a word you don’t know or think is hard and it’s not on the list, you can put it on there for the others. So it’s not a pre-existing one. That probably makes it more useful though
