Our Multiplication by Heart flash cards can help you master multiplication facts and achieve true fluency, with just a few minutes of practice per day. Every card has a meaningful visualization that can help you understand different ways of representing multiplication: from repeated addition to arrays or prime factorisations.

New cards start in box A. If you answer a card correctly, it moves to the next box, otherwise back to box A. Every day, we will pick between 20 and 40 cards for you to solve: some may be new, and some you may have seen before. The delay between seeing the same card again increases as it moves through the boxes. This process is called spaced repetition, and helps ensure that all facts reach your long term memory. You can learn more in this video.
