Last year we enjoyed a unit study on China.   It's main purpose was to have fun dabbling in another culture for awhile.  This year, for Chinese New Year, we revisited the study and took it deeper.  Here you'll find ideas to supplement a study of China.  I'll post more as time permits.   Don't forget you can always ask a unit study questions at Kaleidoscapes. This is a great board to discuss unit studies in general and to share resources with each other.
