Multiplicação de Coração

Settings and Instructions

Rote memorization of multiplication facts is often disconnected, boring, and hard. Multiplication by Heart was designed to help you master multiplication facts in a meaningful, connected way. Using the flash cards for five minutes per day will help you understand multiplication and achieve true fluency.

We’ve layered meaningful visualizations into the cards, so that you can understand and connect different ways of representing multiplication. Deck 1 introduces the idea of multiplication as repeated addition. Deck 2 takes us to the more advanced and absolutely central visual of arrays. Deck 3 is based on prime factors and the visuals come from the board game Prime Climb.

We use spaced repetition to ensure that you re-remember facts you were about to forget, at the optimal time to plant them firmly in long term memory. Every day, we will pick up to 30 cards for you to solve: some may be new, and some you may have seen before.

In shuffle mode, you have access to all cards at once, but we do not save your progress.
