The Classical Historian has produced a number of supplemental resources that are useful whether or not you are using other Classical Historian curriculum.
Go Fish Card Games in your choice of Ancient History, Medieval History, American History, U.S. Presidents, or Constitution can be used to play either Go Fish or Collect the Cards. Each deck has 12 categories with four related cards per category. With Go Fish, players try to collect cards by categories. For Collect the Cards, players use a series of three hints on each card for a quiz/review game. History cards can also be used to play Chronology (arranging cards in time sequence) or Geography (organizing cards by geographical area).
Cards are beautifully illustrated, color-coded, and numbered. Card decks come packaged with a small booklet that explains the rules, but this booklet is also loaded with further information regarding each card. For example, while U.S. Presidents cards list three key pieces of information, the booklet has a lengthy paragraph about each president.

Memory Games for Ancient, Medieval, and American History are patterned after popular memory games with paired sets of square cards. These seem most useful for younger students, but older students will probably enjoy the more challenging games that can be played with each set.
American History Flash Cards ($9.95 per set) are three separate sets of cards covering from early American history up through the beginning of the twentieth century. Each set has 52 cards, and each card has two questions with the answers on the reverse. These can be used for review, but I think they would also serve well as “trivia” questions used with any game board with a path.
