Multiplication by Heart was designed to help children master their multiplication by using the flash cards for 5 minutes a day to achieve true fluency. Multiplication by Heart is a deeper, more connected, more visual way to learn. We take advantage of the science of memory to make sure you're getting the facts down, accurately and quickly. And you understand what the questions mean visually, as well as how to get the right answer. Plus, there are games, puzzles, and explorations to take the learning further, all while having fun!
