Extending Mathematical Power (EMPower) was created to integrate the best of K-12 mathematics education reform into the field of education for adults and out-of-school youth. EMPower was designed especially for those students who return for a second chance at education. Over the course of four years (2000-2004), a collaboration of teachers and researchers with expertise in adult numeracy education and K-12 mathematics reform developed the EMPower curriculum units. Teachers from Arizona, Maine, Illinois, Massachusetts, New Jersey, New York, Pennsylvania, Rhode Island, and Tennessee piloted lessons. From 2012-2013, teachers in New York piloted revised EMPower lessons.
The EMPower book series were was first published in 2005 - 2006. In 2016, three of the EMPower titles (Using Benchmarks, Split It Up, and Everyday Number Sense) were updated and enhanced. All titles in the series align with the College and Career Readiness Standards for Adult Education.
