This is a great project for your preschooler that promotes fine motor skills.
plain sheet of paper
cookie sheet (for easy cleanup)
On a sheet of wax paper, draw small circles with a permanent marker. (In the picture above, you can see that I made several shapes out of small circles to fill in. In the picture below, I drew small circles in 4 straight lines). Place a piece of white paper underneath the wax paper (to make it easier to see) and then place that on a cookie sheet to avoid any spills. Put a few drops of coloring dye in a mug of water. Then you are ready to go. I always encourage my son to to go nice and slow and concentrate on making a dot in the middle of each circle. My son really enjoys these eye dropper projects.
