This problem has been inspired by "The Man", a story by Raymond Briggs, which you might like to read.
The Man is much smaller than you and me.
Here is a picture of him standing next to a mug.
Can you estimate how tall he is?
Can you think of something that you have at school or home that is approximately twice as tall as the Man?
What about something that is about half as tall?
How tall do you think the Man's mug might be?
Can you estimate how many "Man mugs" of tea might fill one of our mugs?
