For one week I'm going to be teaching music at a vacation course for kids. How can I effectively teach the basics of music to kids aged 5-12? I know it's very little time. The coordinator wants them to be able to play 1 or 2 songs at the end of the week. I don't know how many kids there will be, but I'm estimating about 10. Is there any method out there that I could possibly use? I really don't have any experience teaching. I'll be mainly teaching piano, but I could also be teaching guitar, bass, or drums.
I'm ignoring the organizer's desire, because nobody can learn to play an instrument in a week. The best you could do is give them all percussion instruments and have them bang along. Instead, try letting them organize it. See if they'd rather sing or make music. Then if you can get the raw materials, let them design their own instruments. Just coach them on rhythm and ensemble playing and see what comes out. I know a teacher who did something along those lines, and several kids invented and wrote out their own musical notation for "songs" they created.
You have a total of 2.5 hours of contact time. Split into 5 sessions, so you'll lose some of that time just settling them down.
You have time to teach them to sing a song as a choir -- and barely time for that.
