This document summarizes the key findings and recommendations from the US National Mathematics Advisory Panel's 2008 report on modernizing mathematics curriculum and instruction in the United States. The summary highlights that the Panel recommended streamlining the K-8 mathematics curriculum to focus on mastery of key topics like fractions that are critical foundations for algebra. It also recommended ensuring all students have access to an authentic algebra course by 8th grade and that teachers need to have strong content knowledge in algebra topics. The Panel found limited evidence that calculators improve math skills and called for more high-quality research on effective instructional practices.
