Book of Mormon Videos- From the Illustrated Scripture Stories, you could just play a few or the introduction one
A Book with a Promise (about 2 1/2 minutes)- Mormon Message- too old for the littlest ones but the older ones might sit through it and like it.
What is the Book of Mormon? (about 1 minute)- A 60 second animated overview of the Book of Mormon.
My Behold Your Little Ones Lesson 22 handout packet includes
5 circles relating to the stories in the manual and how the Book of Mormon teaches me about Jesus Christ. Punch holes into the sides and string them on a necklace. You can even string cut straws in between the circles if your children enjoy lacing activities.
Book of Mormon Figurines- Here are also Abinadi and King Noah, Nephi Builds a Ship, Alma and Amulek, Joseph Smith. Use them to tell a story from the Book of Mormon in the lesson; have the kids make them into puppets, hide them around the room and play "hide and seek" with them then tell a little about them.
Mormon and the Book of Mormon- A rebus story (story with pictures for word) so you can teach them how to "read" it a little bit. Make it into a little booklet or into "Gold Plates" by using foil as the cover.
Book of Mormon Times and Today- Match modern pictures up with scripture pictures. Could also cut these pictures out and make something like a lei necklace- use straws and fruit loops with them.
Book of Mormon Animals- These animals can be found in the Book of Mormon (references are provided).
The Book of Mormon is a Great Book- Poster of a family reading it- turn it into a puzzle or use it as a visual
A Voice from the Dust- Love the visual on this poster- talk about how the plates were buried until Joseph was ready to translate them
Publishing the Book of Mormon- How many copies of the Book of Mormon can you find or use it to talk about how it was printed
I Will Read the Book of Mormon- Reading chart but use it as a gluing activity instead if you are up for it!
I Know the Book of Mormon is True- Hidden objects
Coming Forth of the Book of Mormon- Mini storybook
Book of Mormon Feast- Another reading chart but fun to just color!
Book of Mormon Coloring Chart- Just use it as a coloring page or glue squares on it or get some stickers to cover it.
