## Let's learn!

**What is an inch?**

An inch can be defined as a unit of length in the customary system of measurement.

Length in inches is either represented by in or ‘’. For instance, 5 inches can be written as 16 in or 16’’.

An inch in metric system is exactly 2.54 cms.

There are two half inches and four quarter inches in one whole inch.

## Let's sing!

*Length of the an old tree so tall,*

*Or the height of the broken wall,*

*Or the length of a ribbon so small.*

*With an inch tape, we measure them all!*

## Let's do it!

Give you child sticks, straws and ribbons of different measures. Ask them to use the ruler correctly and note the length of each in inches. Explain how much a quarter or half inch measures.
