Yesterday was wrought with small, bothersome issues in the school house--why?
I have to continually remind myself that it's critical not to entertain small matters during the busy school day--it's best to stay focused on the students and the learning during the day, and put those small bothersome issues on hold until you can give them needed time and thought.
Yesterday I let a number of those issues seep into the day, and that created havoc.
Good planning, good communication, and focus on the essential elements of the day helps you to stay clear of issues that get in the way and confuse the goals. Those issues can wait until there's time for better and more focused attention before or after school. Don't forget.
