Ninja Rowson is one of the best maths teachers to have. He will perform a dance called the Ninja dance where he moves around as If he was a ninja whilst impersonating a Chinese/Japanese accent. He is a good teacher although sometimes he gets in a strop and sits back down in his chair for around 10 minutes of the 60 minute lesson you have with him .
