My oldest (DD) did not particularly enjoy the Pathway readers, but my 2nd child (DS) loves them! He is over halfway through the last 2nd grade book. We are not doing the workbooks either. My daughter went through Harriette Taylor Treadwell’s readers through the 3rd grade book. There are different things I like about each.
Pathway readers for the most part follow a family and add new characters with various stories. The stories are interesting and engaging. They teach moral lessons as well as good reading by repeating new words several times so the child learns to recognize them and read them fluently.
Treadwell readers offer a mix of stories, fables, and poetry so the child learns to read various types of works. The stories are also interesting and engaging. Some are lengthy, so we just break it up over several days. Words are not repeated like the Pathway readers, so I had my DD re-read poems until she could read it confidently and fluidly. Some of the words gave a vocabulary lesson as well since they were unfamiliar.
