The document outlines the weekly library schedule for three rotations. Rotation 1 schedules the 1st, 2nd, and 5th grades with no 4th or Montessori classes. Rotation 2 replaces the 1st and 3rd grades with the 4th grade and maintains the 2nd and 5th grade slots. Rotation 3 removes the 2nd and 5th grades and replaces them with the 4th grade while keeping the 1st, 3rd, and Kindergarten times.
