I have learned many things about myself over 15 years of teaching and one is that my desk is my visual To-Do List. If my desk is clear I feel like I have nothing to do ... Unfortunately, that means when it is the end of the grading period, my desk is piled high.
I have also learned that visual learners often struggle with a planner, because once you close the planner those items no longer exist. This hits home with me.
