Our home school children enjoy learning through playing games. They can play Professor Noggins games and learn without feeling like they are being drilled. It makes history learning fun rather then tedious. This game has easy and hard questions. Once they master the easy questions they can go on to the harder questions. This makes me feel like I'm getting double my money's worth. My children are in the 3rd, 4th, and 5th grade. This game is great for 5th grade American History. The younger children can also get a jump start on their history as well.
