Reminders: 

1) Videos for each HW.  Be sure to look in the instructional videos section for the videos assigned for each HW.  You will be required to either fill in pre-made notes or make notes of your own if no pre-made notes are provided.  These notes are to be titled and turned in with the HW in order to earn credit for this part of the HW.

2) For ALL HW you need to include a vocabulary list of pertinent vocabulary from each new section you turn in work on.  Label which vocab is from which section to earn credit.  Vocabulary should be defined in a way that helps you, personally:  words, pictures, formulas, etc.  (Any section already completed you do NOT need to redo vocabulary.)  

3) For book problems, see HW guidelines (link above) on how to do this work. 

Remember: Continue to do vocabulary for EVERY new section we cover and turn them in with the HW.
