How to manage 15+ Czech five year old kids in your classroom, if you only speak English? It´s easy, no worries. You need a clear and structured lesson plan, you need to be a leader and you need to show a big warm smile. Use body language too and you will succeed. Children love to be surprised, entertained, they love physical activities and once you do all of it, you can introduce and drill any language you like, even comparatives.
