Why I write postcards to all of my students

For the past couple of years I have written every student a post card and given it to them on their last day of class with me. I think it's a nice gesture because I genuinely feel like I have real love for every single student, and I want them to know that I feel that way, Also, I have noticed that when I know I am going to writing post cards to students I treat my students a bit differently. I make an effort talk to every single student and get to know them on a personal level, instead of just the rowdy or outgoing students.  I keep notes about the things that I talk to them about so that I can remember to ask them about it again later and remember to write it in their post card. I truly believe it helps me and them connect better. I also truly believe that you can get anyone to do anything (including miserable math) if they know that you truly care about them.
