We’ve got a new take on addition flash cards. It’s a deeper, more connected, more visual way to learn, so you understand what the equations mean, as well as how to get the right answer. We take advantage of the science of memory to make sure you’re actually getting the facts down, accurately and quickly. And we have games, puzzles, and explorations to take the learning further. Don’t learn by rote. Learn by Heart. Excellent for gifts, from Back to School in Fall all the way to Christmas!
