The Rosary Center's website contains simple written instructions for praying the rosary. HolyRosary.org gives more detailed information about the rosary and also offers an interactive rosary that lists which prayer should be recited with each particular bead.
The rosary is a popular meditative prayer used primarily by Roman Catholics. There are three basic prayers that a person must know in order to pray the rosary: the Our Father, the Hail Mary and the Glory Be. The person recites the Our Father on the larger beads and the Hail Mary on the smaller beads. He recites the Glory Be between each decade, or 10-bead section, of the rosary. While reciting the prayers, a person reflects on a particular mystery, or deeper theological meaning, in the life of Jesus Christ.
A typical method of praying the rosary on a regular basis involves using an assigned set of mysteries for each day of the week. For example, on a Monday the person reflects on the Joyful Mysteries; the events surrounding the birth and childhood of Jesus. On Tuesday the person reflects on the Sorrowful Mysteries; the arrest, trial and crucifixion of Jesus. The beads of the rosary and the prayers said with it are essentially used as a time-keeping device, allowing adequate time to reflect fully on each mystery as the person goes through the rosary.
