In this study, I have attempted to introduce Patterns' in teaching algebra at the lower secondary level in a Government school. The study was conducted in one of the government schools in Karachi. The purpose of this study was to find out the possibilities and constraints in using patterns' as a technique in the teaching of algebra. The study was based on the qualitative paradigm of research. It was designed as an action research, and carried out in the form of case studies of three mathematics teachers of the lower secondary classes. Among the major findings of the study was that teaching of algebra through patterns' can improve the quality of teaching and learning in the mathematics classes. The use of patterns' can also contribute to positive changes in the attitudes of teachers towards the teaching of algebra, and likewise the attitudes of students towards learning of algebra. The study takes note of some of the constraints and challenges in using patterns' in teaching algebra, and makes recommendations for introducing this method to the teachers and students of mathematics.
