## 'Hand Span' printed from http://nrich.maths.org/

Spread your fingers as wide as you
can,

What you have now is called a
**hand span** .

A hand span can help you to find
out how big

Is the height of a cow, a horse or
a pig.

Use your hand span very carefully
and see

How many it takes to go right
round a tree.

Now get a good friend and make
this a game,

Compare if the number of spans
round the tree is the same.

Next find an adult and compare
their hand span too

To see if they use more or less
spans than you.

Now write down the answers and
think as hard as can be,

Why is it better to use a tape
measure like me?
