A children's puzzle with ten or fewer pieces (a puzzle of a church would be helpful -- you can easily make one if necessary) and a flat surface on which to assemble the puzzle.
Do you like puzzles? I have a puzzle for us to work together this morning. I'm going to need your help. (Distribute puzzle pieces and assist the children as needed. Be sure to withhold one piece of the puzzle.) I can't wait to see our puzzle when it's finished!
We seem to have a problem. Our puzzle is not finished; it has a hole in it. It doesn't look right without all its pieces. Does someone have the missing piece? How can our puzzle be complete if we are missing a piece? This is disappointing!
