Nikolaos Petrou
Math Teacher
Making the abstract make sense
Secondary mathematics teacher with ten years teaching algebra through calculus to students aged 12 to 18 in Athens. Plans lessons that build genuine understanding rather than rote rules, and is known for turning around students who arrived convinced they couldn't do maths. Lifted his classes' university-entrance exam results above the school average for three years running. Differentiates for mixed-ability classes of 25, runs a popular after-school problem-solving club, and mentors two early-career teachers. Calm, methodical and patient with the students who need it most. Looking for a mathematics teaching post at a school that values deep understanding and strong exam outcomes alike.
