Meredith Powell, a 24-year old math teacher at Lincoln High School in Tacoma, is accused of seriously inappropriate behavior with two students.
According to court document obtained by KIRO, Powell allegedly gave a blow job to a 15-year old student and had "sexual contact" with a 16-year old… all while the rest of the school was attending an assembly last month.
The alleged incidents took place in Powell's classroom, giving a whole new meaning to The Pythagorean Theorem.
Powell pleaded not guilty on Friday to counts of third-degree child rape, along with one count of communication with a minor for immoral purposes.
The latter charge was based on Powell supposedly sending one of her students a nude picture of herself in a bathtub via Snapchat.
Tacoma police became privy to Powell's actions after she wrote a letter to one boy’s girlfriend apologizing for “promiscuous” and “unprofessional” drunken text messages she exchanged with one of the boys.
The teacher was placed on paid leave Wednesday and arrested Thursday.
She isn't the first teacher, of course, accused of sex with her students.
