A fabulous someone on Facebook posted this 4x6 "bingo card" of the prophet and apostles (find the original posting HERE if you are part of the LDS Choristers Facebook Group. You can find out about joining HERE if you're not!):
She suggested uploading the picture to Costco for 13 cents a piece (to download, click on the picture, then right click on the image and select "save image as." Save it somewhere on your computer then upload it to print at Costco or wherever you send your pictures!). Then use it to play bingo with candy pieces. In between each name that you call out, you could give a brief description of each of them and then sing The Books in the Book of Mormon but use their names instead. You can find details about singing it HERE (scroll down a little into the post)
Then the kids can take these home and cover each picture with candy (or whatever) as they see these men speak during Conference. Brilliant! I can't wait for my own kiddos to use these!
