Mr. Zack is a math teacher. He's not the youngest teacher in the school, but he is amongst the younger ones. As a math teacher he may seem annoying to his students because of all the formulas and bunch of homework and writing all the time, but it's because he cares. Mr Zack cares a lot about his students, he wants them all to have fun in his class, but also learn. He can also read people pretty good and he trusts his gut.
Mr. Zack was heading to his classroom after spending a few minutes in the teachers lounge. He's peacefully walking down to his class as he checked his schedule, aha, he has sophomores now. He went into the classroom and closed the door as the students settled down.
"Good morning everyone." Mr. Zack said with a smile as he went over to his desk.
