This paper formulated and discussed a Method Combination Therapy involving concept map and target task approaches to teaching factorisation of quadratic expressions to secondary school students (age 15 to 16). The paper considered the Type A and Type B forms of quadratic expressions making clear distinctions between both. The quadratic expressions having been factorised were applied to finding the solutions to quadratic equations. Sufficient activities were presented for both the teacher and the learners for mastery. The Method Combination Therapy is recommended for wider publication and usage in of teaching algebra in secondary schools.
