The original schoolhouse remained at the Sand Street ( California Street ) site for many years , while in continuous use . After the high school moved out , it became a school for the lower grades . It went completely unharmed by the Long Beach earthquake in 1933 , which did a lot of damage to the newer buildings in downtown . By April 1936 , nearly 300 children attended school there
