If you want to get teenage boys excited about talking about something en español (or any language), ask what their dream car is. Find a picture on Google images and put it in a powerpoint. Label the parts and ask how many there are, what kind, etc. Then brainstorm as a class in a Word document negative commands--we got "don't paint it brown" and "don't throw balogna on top of it." LOL.
