It is important to make sure the students clearly understand how they will be evaluated before the activity begins

Make sure the grading system is fair and given to the students at the begininng of class. Extra credit with too high a point value can be used to replace regular assignments that are essential to learning.

Always have a plan B ready and use assesments to gauge the students knowledge before class begins.

Use the 10/20/30 rule with powerpoints. Don't use too many (more than 5) points per slide. Use a large enough enough font so that the students can read it easily. Be careful not to just read from the powerpoint

It's important to arrive early and prepared. Also to observe other teachers and to make adjusts to my teaching style based on the reactions from the students
