โจทย์ปัญหาคณิตศาสตร์

This is a good example of using English. Makeup ten easy math problems for the students to do. Remember, this is testing their English and not their math. A good example would be: “Five pencils cost thirty-five baht. How much is one pencil?” Once they are used to these kinds of questions give them a strict time limit of only 10 minutes. This will force them to think in English. It is a mistake for them to translate into Thai first, work the problem out in Thai and then translate back into English.
