What is supplementary?

Supplementary refers to something that is added to or complements another thing to enhance its value or effectiveness. In the context of education, supplementary materials are any resources that are used alongside the primary curriculum to supplement or enhance student learning. This may include textbooks, workbooks, online resources, educational videos, and other related resources. Supplementary materials can be used to provide additional information, offer alternative explanations, provide further examples, and reinforce key concepts. They can be particularly useful for students who need extra support in a particular subject or for those who are more advanced and need to be challenged.
