Does your child waste time reviewing facts they already know?

The Leitner Box is a spaced repetition system. Abacus teaches children to focus review on what they forget.

Here’s the promise: You’ll learn how to supercharge memory with flashcards.

🧩 Why the Leitner Box Works

It schedules reviews at increasing intervals, focusing effort on what you’re about to forget. This is the most efficient memory system.

🎯 How to Make a Leitner Box

Get 5 boxes or dividers. Label 1,2,3,4,5. Make flashcards: Question on front, answer on back. Start all in Box 1 (daily review). Daily review: For each card, if correct → move to next box. If wrong → move back to Box 1. Schedule: Box 2 = every 2 days, Box 3 = weekly, Box 4 = every 2 weeks, 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.
