For teaching clothes, I asked my students to listen a song about clothes at the lab. They could identify different clothes by singing this song http://www.youtube.com/watch?v=cFWm1sUCD_g
After that, I used realia for teaching them clothes and colors using a clothes line.
I asked them these questions: What is this? or What are these? for teaching singular and plural.
Finally, I asked them: Do girls wear dresses?
Do boys wear pants? Do boys wear skirts?
Students answered Yes, they do or No, they do not.
