Hi, @Edie Bush!

We don't have anything specifically about the Transfiguration at our site, as Rotation Modelers teach "major" Bible stories for four or five weeks in a row, thus, "minor" story topics may not have much in them. But we do have some resources that will help you teach Matthew 17:1-8, Mark 9:2-8, and Luke 9:28-36:

• For an object lesson, you can incorporate some of the special effects described in Making and Using a "Galaxy," "Nebula," and/or "Star Field" "Night time" Projector for Drama. Let the students help you create the light and clouds and retell the story. Talk about signs and how this event was a sign to the disciples that Jesus is God's son.
• Or here is a suggested game where Jesus is compared to a superhero -- Jesus was Transfigured on a high mountain top, Superman does a quick change in the Daily Planet broom closet. The ideas in this lesson could be expanded into an object lesson.
• An art project can incorporate illustrations from our Annie Vallotton collection of Bible images (I am sharing smaller images in this post. You can see larger versions, including color, that can be projected here). Have the students add themselves to the story after you have a discussion about how Peter reacted to the situation and how they might have reacted. What did the voice mean saying "This is my Son, my Chosen One, listen to him!"? What does listening to him look like in everyday life?

• And don't miss this opportunity to talk about who Moses and Elijah are. There is a bit of background that you can draw from here.

Hi Edie!
Adding to what Amy said...

Though I'm a Rotation Modeler, and we've never had Transfiguration as one of our four week stories, I have taught the story with kids in our Wednesday night fellowship. We used it in a series of lessons about "how to worship." We taught the story of the Transfiguration then gave the kids a bunch of building materials and told them to "build a booth" (booths in Jewish tradition were small shelters symbolizing and functioning as hospitality/welcome. See Feast of Sukkot.)  But then we had a "Jesus" figure stand up with a shining light on him. Most of the kids didn't stop building and barely looked up because they were "busy" fiddling with stuff. That led to a discussion about "being in the moment" and not just sitting there "coloring" or fiddling during worship --or they'll miss what's really important.

I think that's what a lot of "crafts" do -- they fill class time rather than focus on the meaning/life application of the lesson. So using that same idea I just described..... maybe you could have your kids build some "booths" as your "craft" like Peter wanted to do --and have some things happen during that building time, culminating in "Jesus" standing in the doorway for a moment without announcing himself. THEN after the craft --list ten things on the board that "may have happened" during the booth building craft (with only 5 of them actually having happened) and have kids write down which five things they think really happened.

Also, chiming in on Amy's "lighting" idea...  use the sequined "mermaid" cloth idea described here to create a "transfiguration" effect (a great memory hook for the story).

When I've taught passages that describe some sort of heavenly manifestation, I teach kids that those "visuals" often describe how we feel inside. One person sees a man, while another sees him as the Messiah. One person ignores God while another is moved in the moment. One person sees prayer as a time to go to sleep, another to feel God closely, etc.

The story of the Transfiguration s one of the terrific presentations found in the SunScool Bible App for Kids.

Look for it in Level 4's Peter stories menu:

• A3-4 : Peter. On the mountain (L4 only) "The Transfiguration"
  Matthew 17•1-13; Mark 9:2-9; Luke 9:28-36; John 1:14-18

The App is free, ecumenical, and can be downloaded for use on tablets, smartphones, Windows, and Mac!    Get the download link and look up the story you need in our Outline of all 170+ stories in SunScool. That page also includes app helps.
