You can have fun and learn from them at the same time.
At the U. S. Government site, teachers and students will find some resources that will pay for themselves.
H.I.P. Pocket Change is all about fun and information, especially coin information. It all started in 1997, when President Clinton asked federal agencies to find resources that could "enrich the Internet as a tool for teaching and learning."
In response, agencies joined forces to form the Federal Resources for Educational Excellence (FREE) Working Group. The FREE group has pooled hundreds of educational treasures and posted them on the U.S. Department of Education's Web site.At the teacher/parent site, you fill find links to the 50 states coin progect which would be great as students are studying the US by regions. Webquests, Westward Journey Nickel Series™ Lesson Plans, the Presidential $1 Coins Resource Center AND financial literacy resources. A GREAT Site. My mind is just amovin'!
