The most effective classroom management is proactive not reactive. How can you be proactive?
One way is your choice of teaching material. Firstly, your materials (ppts, songs, stories, games etc) should be appropriate for your students’ age and graded to their English level.
Next, you need to choose materials that appeal to a child’s eyes, so it should be bright, colorful, fun, funny and even cute. Take a look at the day-to-day books, tv, movies and songs these children regularly enjoy and consume as idea of how your materials should look.
Having appropriate and engaging teaching materials sets you up for a successful class.
