Resources for polygons in Primary

Hello, for today's post I have prepared some resources for Primary teachers when they are explaining in class the POLYGONS. 

This first one is a song, in which it is explained the main characteristics of each polygon. In my opinion, when the kids are listening to a song, they acquire meaningful knowledge because at the same time that they sing and have a goos time they are learning and revising contents. 

Here we have another one, with the same concepts. Maybe we could use it when they get tired of the same song, so we can play this one and continue revising polygons but with another rythm and song. 

Another good resource in my opinon, to revise polygons is this didactic game. We could develop it when we go to the IT classroom, and we could divide children by pairs, so they could help each other and acquire a significant and relevante knowledge. 

In this game, what they have to do is to match the pairo, for example if they see "square" they have to click also on the place where they think that the square is. They have many opportunities.
