Song: I'm Glad to Pay a Tithing (children songbook p.150)
Lesson: JBody will talk to the kids about tithing and what it is. He is going to give the kids 10 peices of candy. He will then asked each of them to give back one peice. Then he is going to read them Malachi 3:10
10 Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the Lord of hosts, if I will not open you the windows of heaven, and pour you out a blessing , that there shall not be room enough to receive it.
After reading the scripture he will pour blessings (whole bag of candy) out to the kids.

I don't know if this is exactlty how he will teach this lesson, but it will be similar.
