This chapter reports on three distinct implementations of conlang projects: one for elementary school children aged 5–10 that was developed with the Centre for Literacy in Primary Education, one as a one-week summer program for secondary students aged about 15, as part of Queen Mary University’s Widening Participation initiative, and one for university students at Queen Mary College that was based on Adger’s experience creating languages for a television series. For each project, the development process, learning outcomes, and project mechanics are described. The projects vary considerably in structure and focus, and are shown to benefit students at all educational levels.
