 In a message posted online, Rock Valley Superintendent Matt Van Voorst says district officials hope returning to classes can bring some normalcy back to students' lives. Schoolrooms aren't ready, though, so students in kindergarten, first and second grades will start classes at a Rock Valley church. Third, fourth and fifth graders will start school in clean, sanitized but unfinished classrooms. The state of Iowa is constructing six temporary classrooms that will be used by students in sixth through twelfth grades.
