My second practice was in the Escuela Secundaria Técnica 30. I was in observation for some days in the first grade but in two groups C and D,  I think that this experience was rewarding  because I could do a better practice than the last one. Actually the idea of follow the use of the book and the use of the notebook was good because is a great tool for  teachers and obviusly for students too.
This was a quite different practice, first of all there were many students around 50, second I had to give three different lessons in more days and finally the relation with the Main Teacher was helpful for me because he gave me a final feedback, which it was worthy for further practices.
