Abstract: In the recent years, there has been a growing tendency towards the use of innovative and active methodologies in English as a Foreign Language (EFL) in order to develop all students’ skills, and therefore, their communicative competence. This dissertation shows the process developed to plan, design, create and evaluate an extensive reading proposal for an EFL Primary classroom whose main purpose is to develop student’s L2 reading habits and skills so that their communicative competence increases. All tasks and resources have been carried out on the bases of the Communicative Laguage Teaching (CLT) approach, in line with the Aragonese curriculum, and complemented by some innovative teaching methods and approaches such as Task-Based learning (TBL) and gamification. The proposal is aimed to improve the instructional effectiveness of the extensive reading program by using active and communicative methodologies. These will positively affect the development of the student’s reading skills and communicative competence. Although it must be proven in a future implementation, the developed proposal may foster the students’ L2 reading motivation. This dissertation shows that this extensive reading project is an effective teaching resource to be incorporated in the 21st century EFL Primary classrooms in order to develop the learners’ reading habit.
