Before I start my classes with my students, I ask them first what is their aim from the classes?
After that, I start to design the schedule that I'll follow for each student according to their goals.
For example:
if the student is a small kid who needs to learn Arabic for reading, listening and speaking, and starting from scratch, I start with teaching reading in addition to learning some vocabulary meaning, so from the very first class, student will be able to say some words in Arabic, after only few classes, student will be able to speak small conversations in Arabic, even we didn't complete the reading part yet, then when we finish learning the reading part, the student will be able to reach A2 level in Arabic.
I engage kids through with colorful ppts, games, and videos.
