Topic work is a way to organize children's learning and language learning around topics or themes of interest. An example topic web on "Wild Animals" showed how different subject areas like math, geography, science, and art could be incorporated. When planning topic work, teachers should consider factors like students' interests and language levels to choose suitable activities. They also need to consider how to sequence activities, identify learning outcomes, and organize the classroom. While topic work can engage students and support language learning, some potential problems are that it requires significant planning and organization from teachers.
