Too many kids learn addition facts by repeating them regardless of whether they understand them. Addition by Heart is different.

Our cards use vivid, carefully designed images to unlock the meaning of addition and make it stick. When you can see why 6 + 7 = 13 (and how it’s related to 10 + 3) you do more than remember it — you understand it. It’s rock-solid knowledge that lasts.

Five minutes a day is all it takes. And once the facts are mastered, the cards don’t go in a drawer. Instead, they transform into a game deck full of puzzles and explorations to keep playing.

Three decks. One beautiful progression.

• Deck 1 – Dice Patterns (25 cards) — Begin with arrangements kids already recognize
• Deck 2 – Ten Frames (75 cards) — Build intuition for how numbers relate to base ten
• Deck 3 – Bar Diagrams (32 cards) — Deepen understanding with a more abstract, powerful structure

Plus: A bonus reference deck for teen numbers, and a built-in learning guide based on spaced repetition — the scientifically proven method that moves facts into long-term memory faster than any other approach.
