Cross Curricular Assessment for Double Digit Addition

A Class Fair
After completion of the Social Studies unit on goods and services, the students will set up a class fair. Prior to the fair the students will
be placed in teams of three to four students. Each team will earn Firebird cards for their acts of kindness and citizenship. Each Firebird
card will be worth three dollars. At the fair, the students will buy and sell goods and services from each other using the money they
earned prior to the Class Fair. When a student purchases good or services they must keep a record of their purchase in their Goods
and Services notebook. The sellers must also keep track of what they have sold using their Goods and Services notebook.
