Multiplication by Heart is a math flashcard system designed to help kids master their multiplication tables while having fun at the same time. From the outset, parents were impressed with the instructions, which they described as phenomenal. At its core, this learning deck teaches that repetition plus visual aids will help kids master the facts to build a lifetime of basic multiplication skills. All the rules are written out and illustrated. It includes a quick start guide that walks you through how to get started day by day. Once you get the hang of it, it’s really easy to continue by adding new decks. Generally, this system only requires between 5-10 minutes a day and makes learning stress-free. There is no pressure on the child to get the answer right or wrong. If they get the answer correct, they move the flashcard to one pocket, and if incorrect, they move it to a different pocket. The instructions explain which pocket they should be working from each day. If followed, all of the cards will eventually be moved into the completed pocket, meaning they’ve mastered those multiplication facts. Once a deck is mastered, there are little mini-games that are explained, again with both words and illustrations. The ingenuity behind the design of this system allows for this product to be something that children can do on their own or with adult assistance. The flashcards themselves are made of high-quality cardstock, and they do not bend very easily. The system comes in a heavy-duty yet compact box which includes all of the dividers/pockets that the children will place the flashcards into as they begin to work the system. Parent reviewers had an important note for their peers. This is a system designed to be used by one person at a time. Since it builds on their multiplication fluency one day at a time, the cards stay organized in the storage box based on their progress. Attempting to have another child use the system simultaneously will not work.
