Learning areas with a video

During the class we have been talking about the importance of the area. For this reason, I have considered this topic such as one of the most important of Geometry. 

This is the reason why I have decided to search for information about this topic. 
We can find out a lot of resources on Internet about that. However, I thought that the best way to teach that will be a video.

If you have a look to it, you will find an interesting explication about areas and how to calculate it. It is quite important to teach this contents to children because they will not consider the areas as an interesting thing to learn.
