📚 As a proud Space to Grow school, Nash Elementary is transforming outdoor learning and wellness and today, curious 3rd & 4th graders brought that same energy indoors as we explored career paths at the #MWRD and the many ways STEAM shapes our work.

A tall, historic red-brick school building with large windows and decorative architectural details stands against a cloudy sky. Several window air-conditioning units are visible. In front of the building, a black metal fence displays bold black-and-white signage spelling out “NASH ELEMENTARY,” with an illustrated wildcat logo at the end. The sidewalk and bare tree branches indicate a cool-weather season.
