Let's measure the length of your steps

Estimation of length and its standardization

Can you estimate the distance between the two walls of your classroom?

Can you estimate the distance between the front door of your class room and the door of your principal's room?

Can you estimate the distance between your home and the school?

Let's work out for the distance between your home and the school

You have made a measuring tape. You may use it to measure short lengths. But as the distance becomes longer, using a 2-meter long tape will make the job tedious, tiring.
 

There is another way to work out the approximate distance from home to school or vice versa.
 

You can use your step to measure these long distances. You simply have to count the numbers of steps that you take to reach the school from your home.
 

But before that you need to find out how long is your step!
