If you are going to play for that age group, I think you will have to choose music likely to be interesting to them, not you. And you want to be interacting with them constantly, keeping them involved. They don't have the attention span for a concert, or even for most of the pieces you named.
I've done quite a bit of this, not on piano but on trombone.
I choose pieces they are likely to know - nursery rhymes, tv show themes, famous cartoons, etc. I quiz them, give prizes for whoever names the tune first, get them to help me put the instrument together, etc. I add my own stories to the music - eventually they will too.
Here's a suggestion for repertoire. Most of the tunes for the Bugs Bunny cartoons were written by that famous team, the Italian Rossini and the German Wagner. Place some transcriptions of those. SHORT! Kids can't handle much. Here are two songs about horses, one by Tchaik (William Tell) and one by von Suppe (Light Cavalry). Which one do you think liked horses best? Here is a song about a dragon eating a mall. The daddy dragon is too fat to fly, but the mommy dragon fights off Mothra. Can you tell when the mommy dragon comes in? (Ride of the Valkyries)
You're an entertainer first and an educator second, and a performer never, with this age group. If you do it right they leave excited about music, not bored.
