National Numeracy NetworkThe National Numeracy Network (NNN) started in 2000. The NNN established four Quantitative Literacy Centers: Dartmouth College, Trinity College, University of Nevada, and The Washington Center. These centers facilitate the sharing of educational practices in numeracy; encourage interest in numeracy among schools, colleges, civic groups, business and industry; and support research and publications to increase the understanding of numeracy. The site contains lists of textbooks, trade books, and teaching resources.
