The second day of our unit we drew a cotton pictorial. My amazing partner traced an enlarged version of the cotton plant from Cotton's Journey.
It was traced in light pencil and I went over it with markers while the kids watched. We talked about each part and what each part does then labeled each part. A few weeks later we added the real boll to our pictorial - just for fun!
This was their very first introduction to cotton! This took us about 30 minutes to complete.
Just a note for the teachers ready - we also said the chants the day we did this pictorial (and every day of our unit).
