We have been using these books for our family scripture reading. They are perfect for kids. The stories are usually not longer than one or two pages and the pictures help keep the kids attention. After we finish reading we ask our kids questions about what we read to make sure they understood it. You can order these books online at www.ldscatalog.com.
They are listed as:
Book of Mormon Stories, Softcover book
Doctrine and Covenants Stories, Softcover
New Testament Stories, Softcover reader
Old Testament Stories, Softcover reader
