I recently started volunteering for Junior Achievement. Volunteers from the business community go into classrooms and present 5 lessons about financial matters.
I have been volunteering in a 4th grade class. The lessons have been pertaining to resources needed to start a business and how to keep track of income and expenses. I had each of them come up with an idea of a business they would like to start and where to have it located. What resources they would need and if it is located in a good location for the resources they need.
The kids enjoy having visitors come into the classroom.
It has been a very rewarding experience.
