The purpose of this research is to provide elementary mathematics teachers strategies that will enhance their knowledge of standards-based mathematics content and pedagogy and to increase parents' and homework help-line employees' knowledge of standards-based mathematics concepts. Teacher participation in standards-based mathematics activities is intended to promote greater access to developmentally effective mathematics instruction for underachieving students. Parent and homework help-line training is intended to provide support to students as they attempt to complete standards-based homework assignments. The project work is intended to impact students' mathematics standardized test scores, mathematics classroom grades, teachers' mathematical content knowledge, and parental support.
