When Mary Jo Norgaard saw a troubling photo on her daughter's phone, she couldn't believe it.
A vulgar word was written at the top of Greece Olympia teacher Sharon Duffy's whiteboard.
News 8 has blurred it out.
"I couldn't fathom a reason why a teacher would be doing this type of thing in a classroom," said Mary Jo Norgaard, a parent.
Norgaard says her daughter told her it was a dirty word game in her american sign language class.
"It was a game, it had nothing to do with ASL," said Norgaard.
The mom went straight to the district last thursday. It sparked an investigation.
On Tuesday, the teacher resigned.
"They are not going to be exposed to this particular situation. The way the School District handled it, it showed children that yeah, you can come forward," said Norgaard.
Norgaard met with the Greece District Superintendent Wednesday afternoon. Superintendent Barabara Deane-Williams thanked the mom for alerting the district.
In a statement to News 8, Deane-Williams said “We are educators and advocates for student achievement and therefore strive to model effective problem-solving, conflict resolution and respect the dignity of all persons when addressing concerns.”
Norgaard says she has received community backlash but has no regrets.
"It was my duty, I felt. People are angry about it but I wouldn;t change my decision," said Norgaard.
The Greece Central School District does not plan to reveal the results of its investigation - citing this as a personnel matter.
It is now searching for a permanent replacement for american sign language at Greece Olympia.
