Have a child pick any word in the verse. Then explain to the children that the word just chosen now "belongs" to the child who chose the verse. He is the only one allowed to say that word while the verse is now repeated.
After repeating the verse, have another child pick a word. Then have the class repeat the verse while both children who have picked words are the only ones allowed to say their respective words.
Continue until each child has his own word that no one else is allowed to repeat. This is a lot of fun as the children must remember which words they may repeat and which they may not. (It's challenging for the teacher too!)
