I posted this on Facebook earlier this evening and a couple of parents asked about getting copies.

I’ve taken out the Snyder-specific details to create a generic version. You can download it here.
The PDF also includes one vertical and one horizontal sticker chart. We use little round smiley stickers we got somewhere. Have the kid write minor rewards in the smaller ovals (pizza, reading time with a parent, etc.) and one big one at the end (typical bigger rewards here have been a toy under $10, a movie, and a bag of marbles) and march toward them with the stickers, starting bottom left and ending up at the big reward at top right.
Everything’s black and white, letter-sized. Should last about a month. You know, depending.
