We use this to keep track of daily behavior when used with a chart (from the Busy Budgeting Mama). Depending on the color at the end of the day, a sticker is added to the chart.
For example, if my daughter gets 4/7 stickers on her chart by the end of the week she is given a "special surprise". This has helped her in learning the days of the week, counting how many days she has left and being responsible for putting up her sticker each night. It has worked well for us!
(The preview is not displaying correctly. It actually shows days Monday-Sunday, not just Monday. Sorry for the confusion!)
I made this two to a page, and usually print out quite a few at a time to have on hand.
