Enyone have good anime for 11 an año old

u could try Lucky estrella its a very adorable and funny anime ^0^

Sket Dance is a good one~

Try Fullmetal Alchemist: Brotherhood, inuyasha and Cowboy Bebop

Snow White with the red hair

I would recommend:
Detective Academy Q
The Devil is a Part-Timer!
Assassination Classroom [pictured]
The Legend of Legendary Heroes

I hope tu find something tu like!~

I think Sailor Moon, o Lucky estrella is for younger audiences.

But anime like Naruto, Fairy Tail, Hetalia, etc are for teenagers, because of boobs..... lol.

Anyways I think Lucky estrella is a good option.
