ESL Teaching and Learning Tips
In my experience with working with 9 year old ESL students, I have found that when you allow them to chose what they want to read and learn, i.e. make learning fun, they will learn faster and develop speaking and reading skills.
Also, if they are able to write, have them start to keep a daily journal and then each day have them read what they wrote to you.
This too, will help them develop better language proficiency.
