Get your students to practice making present simple sentences whilst also having to elide sounds in connected speech e.g. "Where duzee work?" in order to make it 'fit' with the rythmn of the chant. Have half the class chanting the text in red on the left with the other half responding with the corresponding text in blue on the right. Beat out the rythmn with a marker on a desk! It's great fun.
Thai students respond well to visuals that are famliar to them but feel free to replace logos of Thai banks with those from your own country.
