Now, this is a concept that is new to me. I found out last week that a colleague of mine uses this method with her class of special ed kids. I had a OMG moment, "why hadn't I thought of this?"!. I looked online and couldn't find much, so I made some worksheets to start the year. Not only will this make life so much easier for my kids who STRUGGLE with the concept of change, but hopefully it will minimize the chance of them being ripped off someday. Now, I know this will require a lot of one dollar bills, but I am hopeful that after a while of working with the basics, we will be able to move up to dollar change. http://www.teacherspayteachers.com/Product/Dollar-Up-Method
