The guide provides teachers of limited-English-proficient students in grades 4-6 with a communicative teaching unit integrating language, math, and computer skills. A model for integrating other content areas with English as a second language contains nine classroom activities, beginning with games that introduce and reinforce math vocabulary and problem-solving strategies and ending with hands-on practice at the computer. Lessons progress gradually from a review of math concepts to classification and categorization of number sets, organizing data to form a database, using the database to organize and manipulate specific lists of numbers, application of the database to problem-solving, and designing and searching a database. In all activities, the teacher introduces the concepts to the whole class and then reinforces and extends them in small groups, in a learning center, and in homework assignments. Specific objectives for each activity are listed. Each activity includes recommendations for grouping and teacher role, a list of materials needed, detailed procedures, suggestions for evaluation, and possible extensions of the activity. Two glossaries, one of mathematical terms and one of database terms, are appended. Suggested references and classroom resources are also noted. (MSE)
