I make students active by pictures at first, it's going to be amusing that they will engage with pictures.

I try to give clear explanation and clarification to students about everything we want to talk about. We have different practices, such as writing, speaking... this would be more engaging and enjoyable for students.

I give them types of practices and ask them some questions that causes them to pay more attention to the lesson.

I clarify meaning of words and pronounce the words. If someone has trouble pronouncing words, I do it again. Writing on the board, giving examples, showing some meanings to them with hands... all of these could help them understand better.

We have controlled practices, for example about " there is/are ", it's good and engaging for paying more attention to not make more mistakes.

We have some practices, like a practice on the board. It causes students to write more accurately in teacher's presence.

These types of practices are more engaging for students, because they are free to think, free to write, free to choose and free with themselves, so they have to do it obsessively.
