are they moving the standards on us again?

Here it comes... hold on to your graduation caps... moving targets in the form of academic standards! This month's flavor... Algebra II. Check out this article presented last summer to michigan principals and consider it a warning shot across our bow (http://mymassp.com/content/michigan_algebra_ii_expectations).

This is exactly why an open source algebra 2 textbook would be highly useful. A flexible/editable textbook can more quickly adapt to changes in curriculum than a static textbook series.
