Frequently Asked Questions
What is the Leitner system?
The Leitner system is a research-backed learning technique that uses flashcards to build long-term retention. It's grounded in cognitive science — specifically the principle of spaced repetition: information moves into long-term memory when reviews happen at increasing intervals over time.
Here's how it works: The system uses a small number of levels (typically around five). Each card sits at a level based on how well you know it. Answer a card correctly and it moves up a level — you'll see it less often. Get it wrong and it drops back down to be reviewed more frequently. Each review happens just before you'd forget a fact — exactly when reinforcement does the most work.
The result is instant recall.
How does CueCards use the Leitner system?
CueCards is built on five levels, designed for short, daily math practice. Every card starts at Level 1 and moves up as your child answers correctly. Once a card clears Level 5, it's considered mastered.
The daily tracker tells your child which levels to practice that day, so each card gets reviewed at the right interval — building real fluency over weeks of short, focused sessions.
How does CueCards build fluency?
- Spaced repetition that targets what your child doesn't yet know: Every minute of daily practice goes to the facts they haven't mastered — never to the ones they have.
- Every card pairs the fact with a visual model: Your child sees why 7 × 8 = 56 — not just memorizes the answer.
- The box is the routine: Cards, workbook, daily tracker, answer key, and parent guide — everything your child needs for daily practice.
Do I need to sit with my child every session?
No, the daily tracker tells your child what to practice, the workbook gives them questions to work through, and the answer key lets them check their own work. Sit with them for the first session maybe, longer if they're 6 or 7 years old and then check in whenever it suits you.
How long should my child practice each day?
Around 10 minutes a day is enough. Short, focused sessions work better than long ones for building fluency.
The daily tracker tells your child what to do: which levels to practice, when to do a worksheet, when to take a break. Just check today's date and follow it.
