The key to effective concept mapping is to demonstrate how various ideas or topics are interconnected. It provides a clear, structured approach to understanding and retaining information, promoting active learning. Concept maps encourage students to engage in higher-order thinking, making connections between ideas and fostering deeper understanding. In mathematics education, concept mapping can be particularly useful in clarifying complex relationships between concepts, helping students visualize abstract ideas, and showing how various topics within a subject are interrelated. Concept maps aid in identifying key concepts, sub-concepts, and their connections, which allows both teachers and students to develop a more coherent understanding of the subject matter. For a unit plan on "Algebraic Expressions" at the secondary level, concept mapping can be used as a tool for organizing the content and guiding the
