Teaching My 1st Lesson

I will be teaching my very first lesson in a 6th grade classroom in less than two weeks. I am nervous, and excited about it. I hope that I am able to balance classroom management and the actual content of the lesson. My class consists of over 30 students, 3 of which are special needs students. I must then come up with various accommodations for these students and make sure that I have the time to work specifically with those students. I am relieved however that my first lesson will be covering a social studies topic, and not mathematics. I am still not confident in my mathematical skills, and dread the day I will be asked to lead a math lesson. I suppose I will feel more comfortable over time.
