This paper reports on a study which explores the mathematics teaching strategies used in a multilingual classroom at technical and vocational education and training colleges in South Africa. Effective teaching and learning strategies are required that will motivate students to study and understand mathematical concepts, as well as engage in both procedural and conceptual discourses. Brijlall showed that in mathematics classes collaborative learning has a higher rate of success than does individual learning. He recommends further study on this teaching strategy. This study seeks to draw up some strategies which lecturers can use to teach mathematics effectively in a multilingual classroom. Effective strategies should lead to better understanding of mathematical concepts with subsequently improved performance in mathematics examinations. Hence, this study is important in addressing the call for greater research in this area.
