The National College of Teaching and Leadership (NCTL) panel ruled that it was both "proportionate and appropriate" to ban her and that her conduct could bring the teaching profession into disrepute.
As well as the exchanges with the 11-year-old boy, Hollingsworth also had Snapchat exchanges with a former pupil.
She was dismissed from the school in May last year for gross misconduct.
In its findings the NCTL panel says she was a 'phase leader' and class teacher at the school.
The panel stated : "By sending messages to an 11 year old pupil, including some messages containing sexual innuendo which could have been confusing to the pupil, Miss Hollingsworth failed in her position of responsibility to that pupil and her obligation to safeguard pupils' well-being."
However, the findings say that she had "shown remorse for her actions" and that after admitting what she had done had said she would "forever regret the actions that I took."
In a statement she had said : "I am shocked and horrified by what I wrote, putting the pupil in an inappropriate position, the school's reputation in jeopardy and my own career, [to] which I have dedicated nine successful years, in ruin."
Imposing the ban on behalf of the Education Secretary, Nicky Morgan, Alan Meyrick, Deputy Director of the NCTL said the conduct of Miss Hollingsworth "was a serious departure from the personal and professional conduct elements of Teachers Standards."
