Handouts can be effective aids to instruction or a waste of paper. Those that lead to frustration may cause some students to transfer their distaste of the handout material to the instructor and may increase boredom and disinterest. Those that are well done will enhance student learning.
You
might consider color coding handouts for
student convenience.
If handouts are not needed during the class
presentation or discussion, you will be wise
to hold them until the end of class.
