There are a number of places with word searches and coloring pages. I like the zodiac pictures at Apples4the teacher.com. You can color them interactively which might be fun for the youngest. I am hoping that they will add sentences too.
Ray at childbook.com has a set of coloring pages too.
There is one 1-37) dot to dot dragon here.
Another source for worksheets, mazes, word finds, and some reading comprehension pieces is Edhelper.com . They even have a weekly review section. I have not decided whether it is worth the annual fee of $19.99 for my family, but they expanded their offerings in general since I last looked.
The reading comprehension in their Chinese New Year collection is new to me, and they have also organized it since I last looked. Then, the last thing I looked has an error in it! One reading piece did say to give hong bao to your parents. I have never heard of such a thing! It would be disrespectful to give hong bao to the older generations I know for New Years! Maybe this is a regional issue but I suspect they just slipped up. It is why they are listed last - most of us don't have the time or inclination to fact check every item on a worksheet and need to have a trusted source.
