From the last memo:
I have had conversation with teachers regarding the performance of their students. It was interesting to note that some teachers know exactly what their students need help with to do better. Can we all say that about each of our students? Do we know the name and average of each student? I hope, one day, every math teacher knows the academic performance of each student in his/her class.
Knowing names how how students are performing is one thing. Knowing averages is something else. Let's see 5 class, 34 kids per class, means 170 averages to know. I better start making flash cards.
