Second Language in Children

They say that children can learn a second language easier than if they were to wait until they were....well, not children. The school where my kids go start to teach Spanish starting at 1st grade. It is a rotation class (like gym, computer, art, music). I think it's good for them. If they can get a good start on learning another language instead of waiting until high school or beyond, I don't see the problem with it. I'm glad their school does this. Their old school didn't do this. I wonder if it is going to become more common in elementary schools. Is it offered in your children's schools?
