Abstract: CLIL refers to teaching subjects such as Mathematics, Physics, Biology, etc. through a foreign language. In this paper, we try to answer the following questions: 1) Can we teach 6th grade Mathematics through English? 2) - How often can we teach 6th grade Mathematics through English? 3) How can we teach 6th grade Mathematics in English effectively? To answer these questions, firstly, we study current 6th grade Mathematics curriculum and English curriculum in Vietnam to find the knowledge and skills that Vietnamese 6th grade students have already acquired and what they have to learn more in 6th grade. After that, we choose some 6th grade Mathematics contents and English contents which can be taught together. Finally, we propose the ways to use CLIL approach to teach those contents effectively.
