I’ve used RME to teach 6 children to read (so far). I asked the same question when my first finished it, and was told “now she needs to practice reading.” It’s worked beautifully for my kids. After I finish the book, that child and I take that same time each day to read together. I’ve used things like the Pathway Readers, and actually, a BJU reading book (like 3rd grade level). We alternate paragraphs, building up to alternating pages (I read a paragraph, then she reads the next, I read the next, etc.) We really haven’t done any more with the phonics rules, and the oldest 4 are voracious readers (the younger 2 are newer at it, but I expect they will be also 🙂 )
