As I like to tell my students, just completing the review guide is not actually studying. Sure they say it is until I ask them how they know if they know the material. That is why I link Quizlet cards to our units. Above you can see one for the Byzantine Empire. Most of them are made by students, but they are often quite good. You can have your kids make and/or use them. You can also play three other games. Above I also have the same set of words in the game Scatter.
