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?
