Each publication in the Eisenhower National Clearinghouse (ENC) Focus series presents a small selection of the Clearinghous collection focused on a topic of particular interest to mathematics and science teachers. In addition to meeting general requirements for inclusion in the ENC collection, curriculum materials in these publications are appropriate to the specific topic of the issue; support hands-on, active, inquiry-based methods of instruction; and are readily available. This issue offers a sampling of useful teaching materials and other resources that promote equity in mathematics and science education. Each entry contains title, author, date, publisher, grade level, target audience, material type, language, subjects, abstract, and ordering information. (MKR)
