I knew a teacher that kept a calendar on his desk. He didn’t use it for lesson planning though. Instead he was marking time until summer. That’s what prisoners do on walls. They mark the days until they go free. But if you’re marking time as a teacher, you aren’t redeeming the time with your students. A parent drops a child off at the beginning of the year and it’s your job to redeem the time and educate that child. It’s your responsibility to see that child progress throughout the year. The child should be a better student as a result of being in your classroom. You are responsible—for successes and failures—and you have an obligation to students and parents to redeem every precious minute you’re given as an educator.
