日本語教師をやりたい

I want to teach Japanese as a foreign language but I'm currently short on resources. I need free material. Any help would be appreciated.


非日本人に日本語を教えたいんだけど教材は必要だ。どこか無料で手に入れられる教材はないだろうか…？

Hey the other japanese thread disappeared but I want to ask something.

I keep hearing something like せい or せ which means something like "fault".  I cant figure out what that word is though I've searched everywhere.  せい、せ、せいじ、せいし... something.  It means like "because of you" or "because of me" something happened.
