Do a quick brainstorming with students by asking students' background knowledge about Halloween day. Draw a mind map with the words and terms that students come up with.
Provide students a fill-in-the-blank exercise of the song lyric. The blanks are mainly the words that are related to Halloween day and its culture, so students will find a correlation between the words that they need to fill in and the words that they brainstormed.
Do a group discussion about other yearly celebrations only exist in the United States or other English speaking country such as Halloween. Make them compare ones in South Korea with those.
