Over the last decade standards-based teaching has become the single greatest push in education. The question for teachers often lies with wondering how and where to find resources that match the standards. The K-12 Mathematics Curriculum Center, funded by the National Science Foundation, seeks to do just that by offering to "inform and assist schools and districts as they select and implement standards-based mathematics curricula." The Spotlight link on the site offers news about all sorts of information related to mathematics education including events and current issues. The true gem of the site are the downloadable curricula for elementary, middle, and secondary grades. Each one comes complete with teacher and student materials.
