Conference Bingo is one of my boys' favorite things to do. It usually only lasts one session, maybe two, but anything that gets them listening is a good thing.
My favorite place for Conference Bingo comes from The Idea Door, but there is also a good one here. Both of them have multiple sheets, all of which have the same boxes but are laid out differently. We use Skittles or M&Ms for our markers.
In this photo, the boys used chocolate chips for their bingo markers because I wasn't organized enough to have picked up candy markers ahead of time. The chocolate left marks on the paper, and that led to my next lesson...
...which was to print out the bingo sheets and laminate them. Use clear contact paper if you don't have a laminator or access to one. I'd gotten tired of printing new ones each conference session anyway. So now, I have them printed on card stock and laminated. They sit in my Family Home Evening box with all my other church-type activity ideas.
