12 Days of activities & Bible stories leading up to Easter. I like this way better than the resurrection eggs I've seen so far--it's more substantive and less contrived, and walks your kid through the story of Jesus leading up to Easter in a really cool way.
Resurrection Cookies. Each ingredient has a bible verse to go with it and tells the story of Christ's death and burial as you and your children make these cookies. Make these the night before Easter. On Resurrection morning, open the oven and see the "empty tombs"! Making these cookies has been a tradition in our home and my boys look forward to this! I let them read the verses. It's precious!
Lenten Sacrifice Ideas and Activities for Kids. Have a classroom bin of "goodbye for Lent - see you on Easter" have children bring in items or symbols of items that are what they are giving up. Don't forget to put out a jar/can or what they are gonig to do extra (service/prayer/etc.) as well.
