Very recently, in the "Australian Association of Mathematics Teachers (AAMT)/Australian Industry Group quantitative report" (2014), concerns were raised that school mathematics is lacking real world application. This report highlighted the gaps between school mathematics and the requirements of the workplace. After interviewing industry representatives to find out what mathematical skills were needed in the workplace, estimation was identified as an essential skill. In this article, the author discusses the importance of computational estimation in "real life" contexts and how the language of precision and estimation can assist students to understand the usefulness of estimation.
