Presented is a discussion on problem solving in general and a description of a specific program, the Lane County Mathematics Project, to teach problem solving. Topics considered include: (1) Why teach problem solving; (2) Can problem solving be taught; (3) What are problem-solving skills; (4) What are some examples of problem-solving strategies; (5) How will these problem-solving materials fit into the regular mathematics program; (6) What in-service education is planned for teachers who use the packets; and (7) How will the programs be evaluated? A content outline for a fourth-grade packet is also presented. (MK)
