Martha Rivera Alanis turned on the video on her cellphone when gunfire erupted about a block from her school in Monterray, Mexico. The video, posted to YouTube on Friday, shows the kindergarten teacher soothing her students as they lie prone on the floor.

On Sunday, Gov. Rodrigo Medina de la Cruz of the northern state of Nuevo Leon presented Rivera Alanis with a certificate for showing “outstanding civic courage” for her actions at the Jardin de Ninos Alfonso Reyes school.

In the video, Rivera Alanis can be heard saying in Spanish, “No, my love, nothing is going to happen, just put your little face on the floor.”

Then, loud bursts of gunfire can be heard on the video. The Associate Press reports that local paramedics later confirmed that the sound was gunmen killing five people at a taxi stand about a block from the school.

Rivera Alanis starts singing a song about the sky raining candy, from the show “Barney & Friends.”

When the children’s tiny heads continue to pop up off the ground, the teacher comes up with the idea to have them all turn over on their backs and pretend to catch the chocolate rain in their mouths.

“I’m going to carry on, of course it is possible,” the mother of two told the AP. “If my 5- and 6-year-olds can do it, it is up to the rest of us to carry on.”
