For those kids who need basic decoding instruction, targeted interventions are important. But for the others, teach reading using the books those students need to read in their other classes. That approach simultaneously builds reading skills, improves content learning, and increases academic confidence.
Above the 30-35th%ile cutoff, I would definitely just give these kids extra time with the demanding grade-level materials. Below that line, and I would want to provide at least some explicit instruction in foundational skills.
