In 1998, content specialists at the Eisenhower National Clearinghouse began a review of the existing ENC mathematics subject list with a task force that has evolved into the present Mathematical Sciences Conference Group on Digital Educational Resources. The goal was to establish a vocabulary that reflected the needs of both K-12 educators and university mathematics and statistics educators. Based on the existing ENC mathematics subject list and with input from the Mathematical Sciences Conference Group, ENC content specialists created a vocabulary list suitable for our K-12 audience that also can be mapped to the Core Subject Taxonomy created by the Mathematical Sciences Conference Group. The ENCdl Mathematics Subject List is a working vocabulary that is mathematically correct, reflects the NCTM standards, and will serve the resource discovery needs of K-12 mathematics educators.
