How do you manage to spark student interest in English with large classes?

A discussion in Teaching English in Indonesia on the SpeakWise Indonesia teacher forum.

A teacher in our community recently shared their struggle with keeping students engaged in a classroom of 40+ learners. We know that the challenge of making English learning exciting can often be overshadowed by curriculum pressures and L1 interference. We’d love to hear your personal experiences and strategies on how you’ve successfully captured your students' attention in such a demanding context. What creativity do you bring to your lessons to make them stand out?
