preschooler advice?

I just attended my kids' PTC today. both my kids attend preschool at PCF sparkletots, their teachers are great & so is the environment. I was told that my 4yo in her N2 class is extremely advanced, especially as compared to the rest of her peers n as a result is mostly bored in class or will lash out towards her classmates at times if they don't manage to keep up with her sometimes. She articulates her speech very well, speaks in full sentences n can problem solve on her own when encountering difficulties, her teacher told me that she has also been actively engaging with them to "teach" the rest of the class. My question is, what would u guys suggest i do in terms of her education? I fear she may completely lose interest in school if she continues being bored due to things not being stimulating/challenging enough Prior to entering playgroup with them, I did think of enrolling her in montessori preschools as she has always shown signs of being bored when things are too rigid or easy.
