Useless, you should find a native speaker or move to the environment. Children sing songs not understanding at all. The result is - speaking and understanding that people are talking about. The only way is native speakers, dialogs, direct payment instead of Rus teachers (with 30 years experience). It's good to have 5 grade in Rus schools or university, but rubbish for children who relocate.
I don't quite agree with you. Native speakers can be great teachers, but not everyone has an opportunity to send a kid abroad to learn foreign languages or hire a native-speaker teacher. I am not talking about so-called teachers, who are in fact just common native-speakers with no pedagogical education or at least teacher-training courses. For young learners I would rather hire a teacher who will get on well with the child. I would look for a teacher who is interesting for the child and can show him or her the way to like, respect and learn a foreign language. In a proper way.
