A combined grade level classroom is a particular educational environment with two or more grade levels. Being a unique environment, teaching English as a foreign language (EFL teaching) in this type of environment is equally as unique. An English teacher works with every class simultaneously, combining direct and indirect teaching. With this teaching system, some crucial language learning skills are overlooked due to the increased amount of student’s individual work that is required. By implementing a teaching material, such as an authentic picturebook, teachers could achieve a more efficient and congruent lesson, language acquisition, and equal development of all language skills. This research aims to explore whether authentic picturebooks could be used in combined grade level classrooms as a (primary) teaching material to decrease students’ individual work and increase direct teaching with all classes. The picturebook The Gruffalo (1999) by Julia Donaldson, will be used during four English language lessons in a combined two-grade level classroom in one Croatian district school. During the lessons, many different picturebook-related activities and tasks will be used according to objectives set by the National Curriculum for the English language.
