Teach When Joseph Went to Bethlehem using scarves. (Unfortunately, I couldn't find the author of this idea. If it's yours, let me know and I'll give you credit.)

Have the children choose from Primary song-themed snowflakes from 2013 and/or 2014
Have a Primary Song Snowball Fight!

Play The Nativity Song Matching Game.
In Week 1, the theme is "The Sacrament is a time to remember Jesus Christ." Teach the song "To Think About Jesus" in American Sign Language. I used this easy visual from Christy's Clipart.
On Week 4, the theme is "Jesus Christ will come again." Try teaching the second verse of "On a Golden Springtime."
