North Elementary School fifth grade students not only gave a presentation to the Somerset School Committee on what they do with computer coding in their classes, but they also took a few minutes to look at the laptop computers of the School Committee members and gave them a few lessons about how to write code. “I can promise you, I didn’t know this stuff in fifth grade, fourth grade, third grade and down,” School Committee Chairman Stu Mahjoory said after a student showed him how to write code.
