The core Chinese New Year words shown one at a time, at a beginner's pace: the decorations, the food, the envelopes, the animals of the zodiac.
A festival lesson falls apart if the class does not have the nouns first. This is the nouns: the red envelopes, the lanterns, the lion dance, the zodiac animals, the things that appear in every photograph of Chinese New Year and that students otherwise have to describe by pointing.
Just over a minute, one item at a time, with space to say each one back. It is meant to run before the longer Chinese New Year videos on the site rather than instead of them - get the words in, then watch the traditions and let students actually name what they are seeing.
