The National Middle School Association (1999) has identified transition programs, interdisciplinary teaming, and varied instruction as three of the five fundamental practices among exemplary middle schools. Elliott Grant Middle School in South Texas combined these practices to create Mathematics/Science Housing (MSH), an innovative program aimed at improving mathematics achievement. In this program, mathematics was the language of science and science enriched real-world mathematics problem solving. Or in mathematical terms, mathematics + science = success for all.
