In this chapter, a framework to design engaging CLIL units that make use of motivational digital technologies is introduced. The framework collects the eight-year experience of the author as a content trainer using CLIL in a university context. The proposal grounds on consolidated knowledge on CLIL training, imports validated knowledge from the gamification domain, and applies it to assess the level of engagement of the individual tasks included in a CLIL unit, as well as the CLIL unit itself. The steps included in the framework guide the trainer to make and justify decisions regarding the selection and inclusion of motivational digital technology based on the level of engagement it produces. The framework will be useful for trainers designing their own materials, adapting or reusing existing ones and assessing the level of engagement that their units can produce.
