Columbus State University’s College of Education is now the home of the Problem of the Week math contest, which was started in 1996 by David Rock and Doug Brumbaugh. The math educators also supply problems and answers that are part of the current White House Math Challenge, a presidential effort to boost interest in math and foster problem-solving skills. Visit our history page for more on these and the companion problem-solving sites here — Algebra in Action, Middle School Madness and Elementary Brain Teaser.

This resource addresses fundamental algebra skills to help students be successful and to provide teachers and parents/caregivers with readily accessible material to support this learning. Whether students are learning the material for the first time or reviewing to master the concepts, these tutorials are progressively challenging to address a wide range of ability levels.
