Here are some materials I used in this lesson.
Not sure if anyone else likes flash card review of your students words, but my co teacher and I always start class by using a flashcard style ppt (단어깜빡이) for the students to practice. (They read English and Korean first, then only Korean and then only English)
I also included a Human Zero game (students read the sentence and then try to match the number on the screen by deciding how many students should stand up.)
