first day of teaching practice

Today day was my first day of teaching practice at Government Girls Highersecondary School Attingal. As per timetable I had no classes, I tried to get substituition periods but I didn't get any. I utilized the time fruitfully by preparing lesson plans and planning activitiesfor pupil. From the overall atmosphere of the school it seems that the students are little bit noisy. I should give more focus in maintaining discipline
