And a couple more ideas...

For younger-/non-readers:
I have used a computer program called "Say Your Prayers, Angelina" (update: out of print). I don't know if it's still available, but it's good.

Also, for non-readers, you could use the A-C-T-S model with colored craft sticks. Explain what the colors mean, then have them select a colored stick. Invite them to say the prayer, then when all are finished have them put their sticks in a basket so they can be used again.

Older students:
Pray the Newspaper. Have students find articles that correspond to the A-C-T-S model. Make a collage of the articles.
