The colourful Enter the Portal series of coursebooks consists of a beginner level for grade 4 and four levels for upper primary school. Receptive and productive skills are carefully developed through a series of integrated activities. Special attention has been paid to teaching grammar with videos introducing new structures, revision lessons supported by additional vocabulary and grammar exercises. The addition of CLIL pages, culture pages, research tasks, competence development and numerous videos make English lessons enjoyable and give teachers the flexibility to adapt their teaching style to the needs of their students.
