Welcome to Lumen Learning’s Arithmetic resource pages. In this resource, you will find useful information that will inform you of the topics covered in Arithmetic, problems sets available, and how to adopt the course if it suits your needs.
Our math content is comprised of two pieces: text – delivered either as pdf or from a web-site, and problem sets delivered through the online homework platform, Lumen OHM. Lumen hosts and supports the ongoing maintenance and upkeep of Lumen OHM so it can continue to be offered as an OER resource to the broader community.
