Our school district is a small, low-income district. A few years ago, our math scores were really low and we felt a lot of pressure. We adopted Everyday Math in Elementary school and CPM's Foundations for Algebra 1 and 2 in the middle school. This last school year (2008-2009), our 7th grade was at more than 90% advanced/proficient and our 8th grade was more than 80% advanced/proficient on the state test. Much of our success is due to being somewhat seamless and having curriculum that spirals and offers plenty of practice mixed with investigations. CPM offers our students a great chance to work daily in a format similar to the state test and retain their math skills through spaced practice and revisiting topics in other contexts.
