Setting a Design Challenge: Promoting the Discovery of the Relationship between Area and Perimeter

As part of Lesson Study research within an initial teacher education programme two mathematics teacher educators worked alongside a group of five pre-service elementary teachers to create a motivating and meaningful problem-based lesson. The lesson promoted Year 5 students' understandings of the relationship between area and perimeter. The results showed that problem-based lessons provide a motivating and meaningful content for student learning in mathematics.
