CEMSE is the institutional home of the authors of Everyday Mathematics (EM), a research-based pre-K through grade 6 mathematics curriculum. Both the work of our tool development group and our research support the ongoing development of EM. Through CEMSE’s efforts the third edition of EM was published in 2007, with an all-new Pre-K program released in 2008. A Common Core State Standards edition will be available for the 2011-2012 school year.
Every year in the US, about 4.3 million students in 220,000 classrooms are using EM.
CEMSE supports educators who use EM through our School Support Services, and by developing ancillary tools to advance the curriculum's mission. In addition CEMSE provides resources for teachers, parents, and students through the CEMSE support site for Everyday Mathematics.
