The Blue School , located in downtown Manhattan, sent Abacus Mom this announcement:

Beginning with a 6th grade in fall of 2015, we will add one grade per year through 8th grade.  Blue School’s middle school will be a natural outgrowth of the bold questions, deep relationships, and creative problem solving nurtured in our pre-primary and primary programs. In the upper grades, students will encounter challenging coursework worthy of their intellectual curiosity, and respond by applying the powerful imaginations and solid academic skills they’ve cultivated in the younger years. Our middle school facility will be in the neighborhood of our beautiful building in the historic South Street Seaport district.
