A Brooklyn teacher was charged with reckless endangerment Thursday for allegedly shoving a 9-year-old student’s face into a radiator.

Sharon Roberts, 40, allegedly yelled at the kid before assaulting him during a July incident at P.S. K369 in Bedford-Stuyvesant, a source said.

“Who the f–k do you think you’re talking to?” Roberts yelled.

The boy reported the assault on Wednesday.

He had been verbally abusive toward the teacher prior to the incident, a source said.

In addition to reckless endangerment, Roberts was charged with attempted third-degree assault, menacing and harassment.
