Subject: Context stories to explain negative numbers

Hello,

I'm a beginning teacher. My pupils are in the age of 12-16. I have to 
explain 
to them to calculate with negative numbers. Now, I know just one context 
story 
which helps. It's a story about a witch with a cooking-pot. The temperature 
is 
regulating by blocks. There are two blocks, red-ones and blue-ones. If she 
puts six blue blocks in the pot the temperature is going down to -6. This 
story is analog at the temperature context. 

My question: Is there any other context story which helps to explain to 
calculate with negative numbers?
