The best strategies to use in teaching ESL to any group of students is to include hands-on learning, role play situations where the students become active participants in the learning, and lots of visuals to reinforce the concepts and vocabulary being taught.

Remember to make the learning fun for the students so that they remain motivated to learn.

Also, remember that you will have to bring in outside materials related to the subject matter being taught as an additional tool to help students acquire understanding and knowledge of the concepts and vocabulary.
