## Little Man

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?

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?

### Why do this problem?

This problem offers a context in which to think about relative size, and gives children chances to estimate quantities.

### Possible approach

It might be appropriate to read the book "The Man" (by Raymond Briggs) with the class prior to working on this task.

Before looking at the problem specifically, it would be worth investigating how much liquid different everyday items hold, for example spoons, bowls, bottles and jugs. This practical exploration could be done in a water tray or simply a large bucket or bowl with small groups of learners.

Once the class comes onto looking at the questions, it is important that you encourage them to make estimations and explain how they arrived at their answer. It may be appropriate for you to share your own methods of estimating, particularly when it comes to the capacity of the man's mug. It would also be helpful to have a mug, ruler and measuring cylinder to hand so that everyone can check whether their estimates are realistic.

### Key questions

How long is one centimetre? Ten centimetres? So how high do you think a mug might be?
