teach with visuals, images.

Show them a film and ask them what will they do in the same situation than the actors in an specific scene. Human beings are very dependent on the sense of sight.

Buy a camera and take pictures, them show it to them and ask to describe each picture.

Video games, they like that, ask why they like that video game.

Also,

Music, ask them what kind of music they like and play it in the classroom. Make them sing with the right pronunciation.

Maps, get a big map of their country and ask the to learn to pronounce each province/state. Repeat this often, it will impress your admin office and parents of the students.

Food, what kind of food they like and how to pronounce it.

Money, what will do with 10 dollars, show them a list of items and the prices.

Good luck.
