The second grade teachers want me to teach a lesson on "What's This?" in which I teach them 5 nouns (since second grade is blessedly book-and-CD-less, my "curriculum" consists of whatever I want with the occassional interference from the school--"I think next week you teach 'What's This?" or "I think tomorrow you do song").
Any suggestions for the 5 most important nouns for second grade students of English to learn?
Seriously, I'm curious.
