Let's talk Kindergarten in Korea

Okay, so, the whole Korean age really does make a HUGE difference. When I start my day, it begins with 6-year-olds (korean)/4-year-olds (western). Not too long after, I make the trek to the first floor for the 4-year-olds (korean)/2-year-olds (western). Enough said. I am to teach them English. They do not understand Korean yet. Moving on through the day I bounce between the 5yo(korean)/3yo(western) and the 4/2 year olds. After the morning session is over, I then play with the 8/6, 9/7 and 10/8 year olds. I am pretty sure the older kids made fun of me the entire class today. So, we played musical chairs. The kids are CUTE! But, wow, I am lost right now.
