I taught for 32 years and never made above 55,000 a year. I also was not paid extra for either of the master's degrees that I earned. I had extra duty, stayed until 5 PM most days and got to school early. I also bought most of my supplies. Many a time I ate lunch at my desk while I helped a struggling student. I showed up 2 weeks before school started in August to get my room ready and stayed a week later after school to close it down, and don't forget the extra in-service I went to (at my expense) in the summer. I LOVED IT!
As a teacher gift, school supplies are great---pencils, notebook paper, gift cards. One year I got a zip lock bag of pecans. I know the kids loved making cookies, but I saw what they did with their hands, ugh! Please, no more mugs.
