This was my bulletin board outside my door last year.
Close up of bubble gum machine I made..
It was made from white and red poster board and silver glitter.
(because I love glitter!!)
Their homework folders had bubble gum labels on the outside.
And thanks to a childhood friend--- who had this in her room when we were growing up. We had a real gumball machine! Her dad dug it out of storage for me and I gave it a fresh coat of paint.. and we enjoyed gumballs ALL YEAR LONG!
Every afternoon if their behavior had been good they could get one gumball before they left for the day.
