We do similar to Tara for geography. It is not very structured. We have the right books and things available and have fun learning about a different country/culture per month.
Some books and things we like:
Geopuzzles
10 Days in… games
Look What Came From … books (which also has a recipe in the back)
Passport to the World
Material World
children’s atlas for that country
Window on the World (to learn of that country’s prayer needs and pray for them) Dover’s Around the World coloring book of that country and flag
Travel videos
They made their own passports out of file folders and color that country on the outline map and draw and color the flag and write the country name. I write in their “travel dates”. The maps are blank outline maps that cover about 1/5 of the page; one continent per file folder page. I plan to add a travel journal sometime when they are a bit older. Mine are 7.5 and 5. So my 2nd grader probably is ready for the travel journal now. This would include written narrations and drawings from the country of study.
If there are any other literature books that go with the country, I add those in as read-aloud, but you could assign independent reading to your older children as you see fit. We also watch travel videos like Rick Steves or Rudy Maxa.
PS, concerning history, our least favorite has been Greeks.
