This is a great activity to introduce and practice the idea of wants versus needs. There are large pictures that you can print and use in either a large group or small group and try to sort them. This generates great discussions! Then there is a smaller version(2 pages) to print that you can have the kids do on their own (cut and glue and sort) to assess their knowledge. I use it around Thanksgiving time when we talk about things we are thankful for.
