Global economic and societal shifts are causing movement from manufacturing economies to knowledge and information industries. As a result, learners must be equipped with the 21st century skills necessary for lifelong skill development and prosperity. Communication is identified as one of the essential 21st century skills for preparing students for complex life and work environments, within the aforementioned knowledge and information industries. Not surprisingly, mastery of mathematics is likewise identified as necessary for students to achieve the 21st century skills. Mathematical communication requires a knowledge of mathematical language. Understanding this language and being able to use it to communicate effectively, bridges the gap between individuals, and allows for an enhanced transfer of information and knowledge. In this article, the authors explore how the Frayer Board can be used as an effective tool for building language acquisition and in turn support the development of students to communicate mathematically.
