Though I'm only assigning pages 20-32, I high recommend reading the rest of chapter 1 for your edification and learning.
FYI Blog News: Edublogs is going to have some scheduled downtime to fix the problem of the inconsistent performance we've had since the host migration. We'll use http://agiddings.wordpress.com to communicate homework and the like starting Tuesday and continuing until they are back up.
Maintenance: We are conducting more maintenance this week starting from 10PM US EST Tuesday 14th October (that's 12PM Wednesday Australia - apologies to Australian/NZ/Indonesian users). We are currently working out the time required. Apologies again for the inconvenience, we are doing this to maintain service and fix performance issues and we can't thank you enough for your continued patience - The Edublogs Team
