Sometimes you wind up waiting in places---just needing to fill time until your turn happens. How can you prepare yourself to entertain your young--or even your older kids, so the time flies?
If you no longer carry a huge bag filled with games, snacks and the other things (what I used to call "my Mommy bag,") then how about a single sheet of paper and pen or pencil? That is pretty easy to fold up and carry all the time.
Fold the sheet of paper into thirds so that only 1/3 shows at a time. The firt person draws the "head" of this creature you will create together. No peeking at what someone else draws. Now be sure that you extend the lines of the neck onto the middle of the paper and hand the sheet to the second artist.
The second person starts at the neck lines and draws the body of this creature, going onto the third section just to indicate where the legs are.
Artist #3 (which can be the samer person as #1) now draws the bottom of the creature.
Unfold the paper so you can all admire--and probably laugh at quite loudly-- what you have created!
