We develop all of the activities for our active learning kits as Google docs with a CC NC-BY-SA license to make it easy for you to make and share your own activities. To create your own version, simply copy the Google Doc and edit the copy. You can access the current Google Doc with all of the Cat Skull Coloring Kit modules at:
