We have two location worksheets on China - one blank (much harder) and one guided (easier). Use them after studying a map of China and getting to know its position within the continent of Asia.
China Location Worksheet
One of two "fact" worksheets on China, this one is a little more freeform and allows children to do their own research, then write about what they have learned. There's also a location activity.
This printable shows a simplified map of Asia, with China's location marked in red. Please note that we don't claim it is completely accurate - but it should give children a good knowledge of China's location, borders and outline.
