Kerboom Kidz Visits Mount

The music was pumping, bodies were moving, and students were smiling. 

Over the course of one week students in grades K - 6 visited the gymnasium twice for a session with the movement company, Kerboom Kidz.  This program brought to Mount by Mr. Bryant and Ms. Triolo and funded by the Mount PT

A had students dancing, moving, and burning calories.  Every student thoroughly enjoyed this program and can't wait to do it again.
