Sum of the Ages

The whole school can take part in this estimation challenge!

Estimate the sum of the ages of all the people in your school. In this challenge, the methods used are much more interesting than the answers themselves. How will you go about it?

Once you have an estimation, try another method and compare your results. Is one method better than the other? If yes, why?
