Decorate-your-own wizard hat craft activity.
black construction paper precut into cone shapes
elastic thread
double-sided adhesive tape
stickers
gel pens (that write on black paper)
glitter glue (optional)
One that's quick & easy is to decorate your own wizard hats, especially for smaller kids. You can precut the cone shapes out of black construction paper, pre-lace an elastic string to go under the chin, and pre-tape the one side with double-sided tape, so they're all ready to assemble, but they're still flat and easy to decorate. Provide a bunch of cool stickers and gel pens that write on dark paper for less mess, and even glitter glue, etc, if you're okay with a larger mess. When they're done decorating, tape together at the seam & wear!
