Hi Anastasia,
I would first start with a relaxed ice breaker of some type to get the students talking with each other and you. Participate in the ice breaker so you can interact with the students in an informal way. Share with your students your professional experience and if possible interject some humorous stories from your experience. This shows the students that you have a sense of humor and that you are approachable.
Be in the class early and welcome the students, try to chat a few seconds with each student. Ask them questions about their weekend, favorite activity, anything to get them talking with you. Learn their names quickly and use them frequently. Be organized and prepared so the students will see you as a professional educator.
Be yourself and project your personality into the class and work to earn the respect of your students. Once you have earned their respect you will be able to establish rapport with them and it is at this time they will start opening up to you and ask for help.
I wish you much success in your new career as an educator. You are preparing the next generation of professionals in your field and as a result you are impacting lives and that is what teaching is all about.
Gary
