I have been reviewing the curriculum and participating in Anchorage School District committee meetings. Of the finalist, I personally like the Singapore Math 6-8 best, however, my favorite for Middle School is Prentice Hall Common Core Middle Grades, Courses 1-3 which did not make it to the finalist list. I like it because of the electronic features and a well developed comprehensive assessment database and exam generator where I can assess by chapter or by standards strands and have data to differentiate and create mini-lessons for those not getting it.
While the school where I teach is part of Anchorage School District, as a charter school, we may pick our own curriculum, and as a teacher within the charter school, select which curriculum I want to use - aside from what the rest of the district is using. I joined in the district committee meetings just to check out curriculum and to be in the loop with what my district was doing with Math curriculum. (I am happy to see Everyday Math go away. I get students coming from ASD traditional classrooms who have been using Everyday Math. They are not usually prepared to work at the level the Common Core standards demand for Grades 6-8)
