I teach the 4 and 5 year olds class at my church and if I need a guaranteed winner of a time filler then I make paper airplanes for the kids. It has always been my number one trick. No other game or activity ever goes off as well as that one.
This brings back good memories...
I. too, taught 4-5 year old Sunday School class as well for quite some time.
We would often have need for time filler at the end of a session so I took the same approach....paper crafts that were easy and fun.
Paper airplanes, lanterns, boxes, etc.
Kids would return the following week and always ask what the "Mr. Steve" craft was for the week.
Thanks for sharing your experience which helped me to relive mine.
