I have no idea what to name this game. Here are several ideas for names, and the ideas will probably give you a sense of what the game is about: Card Capture; Guess the Back; Collect Points for Knowing Stuff; Actually I Am Terrible At Naming Things, You Name It Whatever You’d Like.
Here’s how to play.
Step One: Take out a bunch of cards from your practice deck that you want to practice. Turn them to the “result” side. Shuffle them up.
Step Two: Deal out a bunch of cards. 4 works well. So does 6. Place them with the products facing up.
Step Three: Take turns. If it’s your turn, you get to pick a card and guess what is on the other side of the card. If you are correct, you get that many points. Meaning, if you guess “6 x 5” and that’s on the other side of your card, congrats, you get 30 points.
Step Four: Etc., that’s the whole game.
The only subtlety is what to do when there are multiple possibilities for what’s on the other side. I think a good way to play this could be that the other person (the non-picker, whose turn it is not) could also issue a guess as to what’s on the other side, and if the picker is wrong maybe they could steal the card? That seems a bit complicated though and what I like about this is how simple it is.
This game only makes sense if you have flashcard decks for every kid in your class, but then again why wouldn’t you? They’re great.
