For this unit, you can use the Food Memory game for any lesson in case you have a few minutes left in class.
I used the Different Cultures PPT for Listen and Speak 1 after I taught the textbook pages.
I took some of these PPT's from previous people, so you can modify it in the way you like.
The Communication Task PPT can be used after teaching talking about fusion food. Basically make a few teams in your class, and have them describe and draw their fusion food. After that, have them make the class vote on who would try their fusion food.
Hope this helps :)
