The Sacrament is such an amazing privilege we have as Latter-day Saints. Through the Sacrament, we are able to renew our covenants with our Heavenly Father and receive a remission for our sins. Three Personal Progress value experiences revolve around the Sacrament, Faith #4, Virtue #4, and Divine Nature #4—the latter including the memorization of the Sacrament prayers.
I have found two excellent printables with the Sacrament prayers that will aid in memorization and can be used as a simple day-to-day reminder of our covenants.
UPDATE 1/22/2015: 
I’ve created copies of the Sacrament prayers that can be printed onto sticky notes (or just cut into 3×3 squares) which will not only aid in memorization, but can be placed anywhere to serve as a reminder of our baptismal covenants.
