The conditions were ripe for widespread participation by New York City students in the national school walkout to protest gun violence: the biggest enrollment of any district in the country, support and guidance from the mayor and schools chief, and a clear winter morning.

So when students began walking out of their schools at 10 a.m. Wednesday, social media immediately buzzed with posts about their activism.

The posts underscored the deep diversity of participation in the city. Protests spanned all five boroughs and all kinds of schools. Elementary and middle schools participated, as did students at high schools. Super-selective schools had organized protests, but so did some of the city’s most struggling schools. And charter schools and district-run schools alike contributed to the mass demonstration.

We’ve rounded up snapshots of some of the many protests. Be sure to watch the videos to capture the full feeling from this morning’s rallies — and please let us know what we’ve missed.
