Think back at your time in Primary. What songs did you love singing? How did they make you feel? Have you taught any of those to your Primary children yet? Now is a great time to do that! And when you do, be sure to bear a one sentence testimony about the doctrine in that song so the Spirit can teach the children. Sometimes I feel like the older songs are neglected, but they are still good songs! One thing to remember, though, is that sometimes the real doctrine in the song is in the second verse, so be sure to look for that and teach that. Using specific methods of teaching, a song can often be taught in 5-6 minutes!
