To make this somewhat easier, the due dates for all Unit 7/8 work will be extended to calendar week 10 (November 10, 2008). The due date for Unit 9 work remains unchanged (also November 10, 2008). In essence, this allows us to complete the combine work for units 7, 8, and 9 over two weeks. This should be somewhat easier than doubling-up two units in a single week. Please note that to further simplify, the quizzes for Units 7 and 8 have been combined into a single quiz activity. This quiz score will count twice. Please read chapters 10, 13, 16, 18, and 19 in preparation of addressing this material.
