Algebra plays a crucial role in school mathematics worldwide, including in South Africa. It is widely applied in different areas of mathematics and science. Algebra uses letters and numbers to represent mathematical knowledge. Many grade 10 learners struggle with algebra because it requires abstract thinking, which can be difficult for those who do not see how it applies to real life. This study aimed to investigate the typical problems grade 10 learners face when simplifying algebraic expressions in a mathematics class. The study was qualitative, and a case study design was followed. Data were collected from 30 grade 10 learners in one high school and one mathematics teacher in OR Tambo Inland District using task-based interviews and questionnaires. This study revealed some common teaching and learning challenges in grade 10 mathematics related to simplifying algebraic expressions. These include the gap between algebra and arithmetic, difficulty in turning word problems into algebraic expressions, teachers not having adequate knowledge about teaching methods, teachers struggling to explain algebra concepts thoroughly and learners finding it hard to work with algebraic expressions. This study recommends instructional techniques to overcome some of the difficulties so teachers can successfully teach this topic.
