Great question! In our area, the bowling alley (Bowl America, don't know if it's a national chain or anything) offers free games in its Rolling Rewards program. It seems like I remember Blockbuster offering a free rental one year; don't know if they do it every year. We have a skate park that also gives free admission for good grades.
Another thing to remember next summer is that AMC theaters offers free kids' snack packs for reading books. It's a summer program; all you have to do is print off the form from the website (they encourage groups to make copies for their members); the kids read three books and write down the titles, and they get the free snacks.
I would love to know about other reward programs out there too!
I don't know of a list, it would be nice, but I can think of one company in particular that does rewards for games and that is Chuck E Cheese. Showbiz Pizza to some.
I am looking for all of the free programs out there for Students to get rewarded for Good Grades. I am looking for websites or info to post in Newsletter so they can take advantage of these. The grading period just ended.
