The post quickly gathered traction with other parents and hours later, Ms Rowland was called by the school's head teacher who accused her of defamation.
Ms Rowland spoke to The Telegraph UK admitting she was "disappointed" in the school.
"I posted the picture on Facebook to see if any other parents were having difficulty with the homework. It got picked up by a few people and I spoke to the headmaster about it on the phone.
"He asked me to take it down because it is defamatory towards the school and that he would have to speak to the data protection officer if she refused.
"I was disappointed, because you'd think a teacher would have a sense of pride in what they are doing. Things like this actually damage a child's education.
