Improving the teaching of invisible culture is a recognised need in the TESOL sector. While there are both scholars calling for a more nuanced focus in classrooms, and teachers willing to take this approach, there has yet been no systematic approach developed for its teaching. This paper attempts to bridge the gap between theory and pedagogical need by proposing that the Natural Semantic Metalanguage (NSM) is a useful tool in ELT through which resources for teachers and learners can be developed. In particular, it will discuss the results of a pilot study into using cultural scripts to teach cultural norms, demonstrate how they can be applied to classroom teaching situations, and discuss how materials can be developed from the theories.
