The "Activities for the Common European Framework of Reference" collection consists of six workbooks to practice comprehension, speaking, interaction, and mediation skills in both oral and written form at all levels of the CEFR (A1, A2, B1, B2, C1, C2). This material offers opportunities for independent work and preparation for official language examinations according to the levels of the Common European Framework of Reference. It is also a suitable tool for students who have specific difficulties with certain skills. Each unit is carefully structured and consists of a warm-up, the main activity, and an extension. Each activity forms a complete teaching sequence, ranging from four to six pages. The books are ideal for use in classrooms, professional contexts, or self-study.
