Credo has an good post on Marian catechesis and effective ways to teach children on Marian dogmas. He also includes some example of this fruit that his students wrote on this topic. Accompanying this post is a graphic that he created titled "there’s something about Mary."
Though I think Credo needs some help and prayers since he also includes a laudatory psalm of praise for Powerpoint. I think this might require an exorcism to excise those Microsoft slide show demons that must reside within. One of the ways to explain hell to a modern generation is to tell them that it is like a Powerpoint presentation that never ends.
