Here is a worksheet to help you and your students through Doctrine & Covenants 42. The second page is the key. Perhaps have them work through it in pairs and then go over it as a class. If you are short on time, give them the verse numbers before each grouping. When going over it as a class, make sure you emphasis the big take away points you want your students to walk away with.
