Designed to support IB Language B ab initio Spanish students, it is the first of two student's books covering the two year course. International in approach and containing material designed to engage older teenage learners, it requires students to think and reflect at a level suitable for an IB Diploma student while placing a strong emphasis on developing intercultural understanding and on Spanish as a world language. ToK and CAS are fully integrated into the learning, all language is taught and practised in context and audio exercises are built into each unit (audio files available in teacher's pack 1).
