So, this is a powerpoint that I used in conjunction with a Bingo board. I gave out blank Bingo sheets and had the kids fill in the names of the 24 countries I used in these slides. We did it competition-style, and the two teams had one representative come to the front, choose a number that corresponded to a slide, and then whichever team wrote the answer on the board the fastest won.
The questions aren't too difficult; my third-graders didn't get stuck or think that they were above their knowledge level.
