One great family bonding that I can suggest for a family who has a small child with them is coloring books. The majority of the children love to paint and color pictures that are create to serve with that purpose. As parents, you can give them a hand in accomplishing this task. Why not give them a portion of your valuable time so that you wont give them reason to be revolted with you for acting the part of being their parents? I, myself adore coloring books. I can envision how my mother and I will try to color pages. She would teach me how to color pictures and what hue should I apply to a certain part of the image. Green for the leaves and red for the petals.... I can still remember the exact picture that we always trace and color.
You can metaphorically take a page out of a coloring book, and break up the work into a few sections. Each team member or group within the team should first be instructed on which part of the page they are going to color, let them know what color they can use, and when their turn will come up. Next, after each team member has finished their part of the coloring than take the completed picture and hangs it up so that every one can see their part of the picture and the entire teams contribution.
