Planning anyone?

Planning: the life of a teacher. I am finding this out rather quickly and rather inconveniently. After a trip to visit the new addition to the family (so beautiful!), I am finally home. I ended the evening with a terrible stomach ache that lasted for a couple of hours--not sure what caused it--and now I'm going to start planning for tomorrow. Tomorrow will mark the first class I teach as a student teacher. It will be the last class of the day. I'm ready and I'm not all at the same time. I am confident in my abilities to talk/teach, but I need to really plan out how to portray the material in a way that interests all learning styles. I better get started....
