6º it´s difficult

I dislike Thursdays, and I think that it´s because the last hour is with 6º of Primary...
I know that it´s a good class, they have a lot to teach me, and I have a lot to teach them...but there are sometimes that I don´t know what to do....
Sometimes I finish with a big headache...
There are students and students...
Tamara, Ángel, Jose, David, Miguel Ángel, Raúl, Jose Vicente...
