NCTM's Principles to Actions:Ensuring Mathematical Success for All (2014) outlines eight teaching practices for effective teaching and learning of mathematics. One of them, Use and connect mathematical representations, involves engaging students in “making connections among mathematical representations to deepen understanding of mathematics concepts and procedures and as tools for problem solving” (p. 10).
