WomanSource Catalog & Review: Tools for Connecting the Community for WomenCreating a strong foundation in math is a good way for girls to assure future economic independence. Professional and scientific occupations are the only jobs where women's earning begin to approximate men's. For non-college-bound women, math skills can enable them to enter the better-paying trades traditionally dominated by men. With this in mind, the Lawrence Hall of Science developed Equals in 1977, a classroom program to promote math education for girls. It supports new ways of thinking about math learning, with an emphasis on the use of manipulatives (blocks, marbles, sticks, etc.), cooperative learning, creative problem-solving, alternative learning assessment and parental involvement.
