11. Length Talk About


The length of something means how long it is. We can also measure how deep, tall, wide or high something is. For example, the length of this line is 4cm.

Important! When you are measuring something you must begin at 0 on your ruler.


If there is a little space on your ruler before 0, just ignore it.
