This document discusses several strategies for teaching mathematics, including group work, self-study, supervised study, and brainstorming. Group work involves dividing students into smaller groups based on ability to allow for greater attention. Self-study requires individual learning without help, while supervised study takes place under a teacher's direction. Brainstorming is a method where students freely generate ideas in response to a topic or question. The document provides details on how each strategy can be implemented and their advantages and disadvantages.
