What do you mean by some phonics? The books don’t teach phonics. They are readers. All of the words in the books can be sounded out phonetically but they were made for teaching look-say reading.
Sorry, I should have been more clear. The books themselves didn’t include any phonics, but the lesson plans that went with them included some usage of phonics, apparently. That actually happens to mirror the way I was taught to read in the early to mid-70s with those books, which was mostly sight reading, but with some phonics.
