As of version 2.7 of CardDroid Math Flash Cards this is easy since there’s a built-in problem set for 12 x [1 to 12], which means to include multiplication problems for 12 times any number between 1 and 12. Just go to the settings screen (tap the “gear” icon on the home screen), tap “Load a Built-in Problem Set,” choose the multiplication icon toward the top of the screen, now scroll down until you see “Multiplication: 12 x [1 to 12] = ?” or “Multiplication: [1 to 12] x 12] = ?” If you want to customize the problem set (for example, to focus on 12 times larger numbers only), follow the instructions below. Happy multiplying by 12!
CardDroid Math 2.6 brings new rewards for perfect scores
It’s here now and it’s HOT! Right now, it’s the #1 educational app and the #83 paid app in the Amazon Appstore and #49 in the NOOK Apps Shop.
Make a perfect score and get a new reward! Some color schemes have poppable balloons as a reward and others have tappable fireworks. (There’s even a secret, hidden “micro game” in the balloon screen. Shhh!) You get spinning stars too.
Update: The most recent versions include micro games on each of the perfect score screens and also unlock a new display style called “doodle” after you spend enough time doing math practice.
