Geography is such a wonderful subject to teach because your children can learn about so many fascinating countries and peoples of the world.A great way to learn about the different countries of the world is by creating a passport and having your children "stamp" what countries they have "visited" or learned about. This passport kit from Paradise Praises has 30 different country stamps, so as you learn about each country your children can color and paste their stamp onto the spot on their passport. This would also be a great activity to do with a homeschool co-op and have the children create country booths where everyone can come by and visit the booth and get their passports stamped.
