I was quite angry with the class as they tool very long time to settle down. I shouted even. I thought they are going back to last year days. Even though, I do not want to scold them, I end up doing so. Meanwhile, I collected the homework. Surprisingly, I received all but two.
In addition, my tablet PC also gave me problem. The minute I turn to tablet mode, the screen became blue.
I taught them the addition of two matrices and scalar multiplication. Since it is only one period, I was rushing to complete. I told one of my student that, I will repeat it again tomorrow.
I reminded the class about their group study lesson in the afternoon.
