Aout 350 pupils carried anti-violence placards and the names of victims of gang warfare.
The marchers were escorted by police on the 45-minute lunchtime walk through Sandys.
Pupils from Sandys Secondary Middle School, Somerset Primary School and TN Tatem Middle School turned out for the walk from Sandys Secondary to Somerset Cricket Club.
Desmond Crockwell, one of the activists behind the Walking Up West march, said “concerning red tape” meant that one school, West End Primary School, did not take part and the start was held up for 20 minutes.
West End Primary pupils held up their messages outside the school instead of taking part.
The children got lunch at the cricket club with entertainment and speeches. Mr Crockwell, who is the chief editor of anti-violence magazine Visionz, said the turnout and spirit at the march was “awesome”.
