Each year I update my USA cards with up-to-date statistics of all USA States and Territories. This game is based off of Top Trumps (copyrighted), but I have far more statistics than the commercial version, as well as color coding to identify States by their region. I use these games with my students and family to practice numbers (large numbers, percentage, decimals) and alphabetical order while learning something about the States & Territories.
Aside from the State & Territory cards, there are also 6 guides to understand how to "score" the statistics. Rules are included, but feel free to play only the statistics you're interested in. My siblings have created their own "house rules" with their families that make it more personal, and I encourage you to do so, too. Drop me a line if you come up with one you think I should know about and feel free to write me with suggestions for future statistics :) If you like these cards, check out my Countries cards. US Presidents and Dinosaurs are coming soon!
