Spider Web Painting

Using a heavy marble, or two, that has been dipped into white paint roll it along black paper that has been placed in the bottom of a box or pan.

Do things by placing the piece of paper in a gift/shirt box and have the children manipulate the box so that marble rolls back and forth over the paper.
It looks like a web!

For the spider I use a brightly colored spider stickers or have the kids use their thumb print which has been dipped into bright paint and use chalk for the eight legs on the spider (thus making it a counting/math activity as well).

Sing Itsy Bitsy Spider for days before and afterwards.
