Our Story

The Outstanding Mastery Guides were developed through the collaborative effort of Rhonda Davis, Darby Jochum, Leslie Hilderbrand and Robert Sheperd.  Together they have 80+ years of math teaching experience.  Several years ago, with school funding and resources limited, they were determined to find a simple, effective, and low cost way to help students retain information.  Thus OMG's were born!  


Initially, OMG's were used as a two week review tool to help students prepare for Georgia's CRCT standardized test. However, after their school demonstrated a 17% increase (75%-92%) in their scores the authors decided to use the OMG's as a method of teaching throughout the school year.  Today OMG's are a way of life at the school.  The authors were so excited about the effectiveness of this tool they felt other teachers would be interested in implementing the program too!
