I done it before. I brought some pan-fried dumplings.( American kids would prefer frid ones) I talked about how to celebrate Chinese New Year. Dragan dance,firecracker, Nian(second tone) monster..etc) Gave them red envelopes ( with chocolate coin, not money) . and explained the celebration of Chinese New Year lasts for 15 days, ending with Lantern Festival. I spent 20 minutes for history, legend.. after that, they were only interested in food...
