I am rather slow in adding a few thoughts here, but for what it is worth…
The Explode the Code series published by EPS and sold by Christian Book Distributors is a good remedial resource. It’s not a series I’d really recommend for all students though it would hurt none of them. The two biggest reasons I’m hesitant to use it regularly is that most lessons follow the same simple pattern and after awhile tend to bore most students. (For those who struggle with reading, this repetition is beneficial.) Also the art work is rather crude (as in simple and basic), it has been done by students. We have used it successfully for remedial work in the lower grades but have never gone further than book 3 1/2 (about the end of first grade, beginning of second grade level). The later books deal with words that many older students stumble over.
