My support time is during seventh period, but I may be able to help you at other times if you arrange to do so beforehand. I also keep a list of paid tutors who work after school hours. In addition, since I do detentions on Wednesday, I am available between 3:10 and 4:10 p.m. on that day. For test make-ups, please see me to schedule times for such.
One way to effectively use support time in my classroom is to use the "Grammar Tutor" program. It is installed on several Dell computers adjacent to my classroom, and has activities that can be done by individuals or in pairs, and the activities can be geared to any level of difficulty, be it Spanish Two, Three, or Four.
