I started with cardstock as the game board, velcro circles, stickers, and some kind of paper punch. (Turn your head since Blogger is being stinky tonight)
Originially I was going to use a ruler to make the grid and figured that's nuts. I just did it in WORD (email me if you want the template) and coincidentally- it would make a fabulous BINGO board. I put a Velco circle in each spot on the grid.
I also wrote in prizes in every few squares as incentive. Two of them are ice cream treat, one is a Barbie toy, two or them are staying up either 30 or 60 minutes later, one is Dairy Queen date with no brother, and the one in the last square is a choice between a new movie (buy one) or going to see a movie at theatre (with popcorn). She seemed pretty happy.
Then I punched out 30 circles (I used circles because it's the first punch I found), using different colors of scrap cardstock. I put a reward sticker on each circle (you know, the ones that say "Dino-Mite!", etc). The back of each circle got a piece of Velcro, too.
So here is the finished project on my still in progress bulletin board:
Look- we have one circle on it already!! :)
