I have been providing my students with my email address to submit their homework and ask questions. This one kid has been sending me jokes. So far, they have been appropriate, however, it's a lot. I would rather him not send them. What do you recommend?

If a student turns in their homework late, should they still have the opportunity to score 100 or should we always take points off for being late?

I teach a 6pm class which is also a long walk from the front door of the school. Many of the students have day jobs and have a hard time arriving on time and then with the long walk to the classroom makes them chronically late. We only have 1 hour so I want to start class on time but how long should I wait to really get started? I don't want the stranglers to miss out on the lesson.

I am new at teaching and have found myself completely drawing a blank after I have covered a topic. I feel like a deer in the headlights or a radio dj with dead air not having a good transistion from one message to the next. I feel like the students are watching me scramble for my notes, trying to find my place in the lesson. Any suggestions?
