Abstract
The main aim of this paper is to provide novice CLIL teachers with advice on key areas related to the implementation of this approach. This is done through the presentation of ‘ten fundamentals’ with their corresponding literature review, activities and suggestions contextualised within the framework of a defined Teaching and Learning Unit, and a final tip, all of which, it is hoped will empower future CLIL teachers in their classroom practice. Materials have been designed by the authors according to the Spanish National Curriculum and the textbook selected to use as an example is: Natural Science 6. In Focus for 6th year at Primary School Level with content designed by Spencer and published by Anaya.
