Sometimes when I'm lazy to organise craft time, I just hand the kids some drawing art paper, colored pens or color pencils and tell them "Here, draw anything you like."
(and stop disturbing me) .
At one of these freehand drawing sessions recently, this is what they drew.
Freehand or freestyle drawing is great. It encourages creativity and gives me more time. The kids will be occupied for at least an hour while they are at it. So, next time you don't know what to do with the kids and they are pestering you every 5 minutes, tell them.. "Here, draw anything you like." ;)
