There is a new and improved Discussion Question section to be used as a warm up. It's a great way to get students ready for the lesson while giving the stragglers time to get into class before the "meat" of the lesson is tackled.
Things have been "spread out" in that what had previously been packed into one or two pages is now in an easier on the eyes, multi-page layout.
Lessons and units are the same, but the order of some of the lessons have changed (therefore, the importance of getting students to download it). This has been done in order to give Tuesday, Wednesday and Thursday the bulk of the heavier lessons - keeping Monday and Friday a little lighter.
There are new and expanded widgets.
Most of all, get yourself familiar with the Teacher's Assistant. She appears on pages here and there and provides useful tips for the lessons. Let me know what you think of her input!
