Does your child re‑review flashcards they already know, wasting precious study time?

The Leitner Box is a physical spaced repetition system. It ensures you review what you’re about to forget, not what you already know.

Here’s the promise: You’ll learn how to build a Leitner Box for any subject.

🧩 How the Leitner Box Works

You need 5 boxes or dividers. Cards start in Box 1. When you answer correctly, move to the next box (longer interval). Wrong answer? Move back to Box 1. This focuses effort on what you forget.

🎯 Building Your Leitner Box

Get 5 boxes or make dividers. Label 1,2,3,4,5. Make flashcards: Question front, answer back. Start all in Box 1. Daily review: Review Box 1 only. Correct → move to Box 2. Wrong → stays in Box 1. Box 2: Review every 2 days. Box 3: weekly. Box 4: biweekly. Box 5: monthly.

💡 A Parent’s Success

“We made flashcards for times tables. My son used the Leitner Box for 2 months. He now remembers all tables instantly. The system forced him to practice what he kept forgetting.”

You might wonder, “Can we use an app instead?” Yes — Anki and other apps use the same algorithm.
