"When I was in seventh grade, (I had) no one at this age to look up to," Craggs said. "This is a chance to talk to younger kids."
Craggs arrived in uniform, including a full backpack to give students an idea of the load he carries while serving. He presented the class an American flag.
In addition to Skype chat, Craggs also received cards and letters from the students.
"I just think it is respectful," said student David Corbeil. "It makes me feel good."
Student Alex Traut liked that he got to know Craggs.
"It's kind of cool to learn about his life," Alex said. "The cars he uses."
Besides spending time at the school, Craggs said he will have a time to catch up with family and friends. The first two things he did when he came home was take a long hot shower and eat a Big Mac from McDonalds.
Student Jonathan Ratjen described the relationship with Craggs as special.
"It's special because he's teaching people," Jonathan said.
