At Grinnell Public Schools, we use the Accelerated Reading program.  In 4th grade I expect all students to achieve a 25 point goal each 9 weeks, which will allow all students to reach 100 points by the end of the year.  If a student earns 100 points by the end of the year, the principal takes them bowling for a reward in May before school ends.
