Colour in these gorgeous Year of the Rat bookmarks for a fun Chinese New Year activity. You could get the kids to write a message on the back - or just sign and date the back - then laminate them for them to give as gifts to parents, perhaps?
Why not colour in a card to welcome in Chinese New Year, the Year of the Rat? It would make a fun writing activity too, and whoever gets the finished card will appreciate the effort that has gone into it more than a "bought" card!
