This is around the time that first year junior high school students should be learning this grammar. It is not a complex grammar point and should be pretty easy to follow.
The lesson is simple but effective in explaining the grammar point. The activity is communicative and also gives the lesson a fun element rather than just the conventional sentence writing practice. The lesson can work well for any sized class and can also be used as warm-up activities if the grammar has already been studied.
