The guide is designed to help educators design math curricula to meet the needs of students of English as a Second Language (ESL) with limited or interrupted schooling in mathematics. It provides techniques for integrating mathematics and language teaching, especially through cooperative learning experiences, makes suggestions for inservice teacher training, and encourages collaboration between mathematics and ESL/bilingual personnel in curriculum development and advocacy for ESL literacy students. The first section of the guide outlines the mathematics literacy goals and classroom environment standards of the National Council of Teachers of Mathematics. Subsequent sections address the following issues: design of appropriate curricula and evaluation; assessing student progress in language and mathematics skill areas; and staff development needs. A series of sample lessons follows, drawn from a middle and high school math literacy curriculum. The lessons are in number concepts and theory, operations, data analysis and statistics, and problem-solving. Each contains a performance objective, vocabulary and materials lists, notes on language issues, notes on the mathematics component, and specific activities or exercises. Answers are included. (MSE)
