Abstract
Poor performance in Mathematics is a serious cause of concern to most countries including South Africa. One of the reasons why learners do not perform well in the subject mentioned is that learners lack conceptual understanding. Algebraic concepts greatly affect development of almost all topics in Mathematics, hence the need to help learners attain deep understanding of algebraic expressions. This study identified common errors and their causes, then suggested ways for overcoming them. The study advocated for the constructivist approach, thus emphasising active engagement of learners to master basic algebraic skills. Eighty-two (82) Grade 9 learners participated in this study. Data was collected using tests and interviews. The study identified: misapplication of fraction rules, incorrect application of distributive property, conjoining terms, misunderstanding variables, sign errors and misrepresentation of exponent rules. Misunderstanding and misapplication of algebraic rules were found to be the main causes of the identified errors.
