To follow-up my reinforcement post, I thought I would talk about token economies (i.e. sticker charts, token boards, etc.) This strategy can be helpful both for parents and teachers. A couple examples might be to use sticker charts at home for performing chores or at school for completing homework. Stickers could be traded for reinforcers, with each reinforcer having a different "cost" (i.e. number of stickers needed to trade in for the item). The ultimate reinforcers don't have to be tangible items and don't have to cost you any money. Maybe your child likes to watch TV or play on the computer. These activities don't have to be "free" - they can be EARNED! Imagine that, right?!
Parents and teachers can easily create a chart using cheap items from the Dollar Store or the $1 bins at Target. These stores often have sections with cheap school supplies, including chore charts, calendars, stickers, etc. You can even make your own chart using your computer (WordArt, Clip Art, Tables, etc.) It's helpful to make your stickers/tokens removable (I LOVE velcro dots and foam shape stickers). For one thing this allows you to reuse the chart, but you may also set up contingencies that stickers can be removed if your child engages in certain behaviors. For example, if your child is a big "complainer" then maybe they lose a sticker for complaining about how many chores they have to do. Google is filled with ideas of sticker charts - take a look for yourself!
