I agree that pupils are derailed when they are given negative numbers. I like this Webquest format.
interesting real life example.
Have to check the URL to the weather forecast.
Alternatively, after assigning the 'country' to the pupils, can give them some websites where they can search for information.
PS: Pupils should be able to carry out internet search to identify one weather website.
By looking at the temperatures of the countries assigned, pupils have an idea of the authentic use of positive and negative numbers.
On the same note, we can also get pupils to suggest "where else" can they find the use of positive and negative numbers.
Through the comments feature, pupils can describe where negative numbers can be found. Examples on the use of negative numbers: The depth that the submarine sinks into the sea, the temperature of ice when salt is added, stock market values, etc.
For interest: In India, the lift numbering follows a number line - Positive number - Zero - Negative number (http://gallery-bangalore.blogspot.com/2007/06/lift-that-teachers-number-line.html)
