When it comes to loving your job, Jan McEntee, otherwise known as Miss Mac, can say she truly does.
"People ask me, 'You're going back? You're going back?' I said yes, I'm going back, I'm not done yet," Miss Mac said.
Miss. Mac is going into her 47th year of teaching third graders, in the same classroom, at St. Mary's School in Sioux Falls.
"We need to bring them into not only a world of knowledge but in a world of their spiritually too and we can do that in the Catholic school system," Miss Mac said.
Miss Mac prepares for the new school year in teacher in-services, alongside her fellow teachers. She says the key to molding young minds, make sure they trust you.
"They have to know that I love them first and they will let me teach them, so it will be about letting them know that I love them," Miss Mac said.
Ken Lindemann a math teacher at O'Gorman High School is getting ready for his 25th year teaching. Even after 25 years, he says he still gets those back to school jitters.
"We all go through it and every year each kid gets through it, it's just a part of the process and it is part of learning, it's to get through the nervousness at the beginning," said Lindemann.
For nervous parents and students getting ready for the first day, Lindemann says remember that hundreds of students before them started the first day with the same anxiousness.
"Try to imagine your success throughout the year. For freshman, don't let the nerves of coming to a new building get to you because, kids have been doing it for years," Lindemann said.
Another important thing to remember on the first day of school, get plenty of rest the night before and eat a well-balanced meal.
