In 1964, national attention was focused on the disenfranchised citizens of the South. In 1989, another kind of disenfranchisement exists, as many poor, indigenous, and immigrant children of color are denied access to programs and teaching that support their success in school. The success of the AlgebraProject stands as a challenge to public school teachers, administrators, scholars, and, most important, those individuals who have traditionally advocated for the democrarization of the society and schools: Will you wage a campaign for mathematical literacy, which acknowledges that every middle school

在1964年全国的注意力焦点都放在disfranchised的南部国人身上，在1989年，当许多贫穷、原位民及其他种族的新移民被拒於学校成功大门之外的同时，另一个disfranchisement也因应立，代数计划的成功已成为公立学校老师、行政人员、学者及那些传统上支持社会及学校民主化的推手的挑战：如果是你，你会不会发起推行学数学的活动让每位中学生学代数且同时赋权给这些小孩的社区你会在「Ella精神组织」工作吗？
